Last Updated: August 2026
Grand Slam titles receive most of the attention when tennis fans debate the greatest players of all time.
But Grand Slams tell only part of the story.
The ATP Masters 1000 tournaments represent the highest level of regular men’s tour competition below the Grand Slams and ATP Finals. Winning them consistently requires players to defeat elite opponents across different surfaces, continents and stages of the season.
So who has won the most ATP Masters 1000 titles?
The answer is Novak Djokovic.
Djokovic holds the all-time ATP Masters 1000 record with 40 titles, ahead of Rafael Nadal with 36 and Roger Federer with 28.
But Djokovic’s achievement goes beyond the total number.
He became the first player to win all nine current Masters 1000 tournaments and then became the first to win every one of them at least twice — an achievement known as the Double Career Golden Masters.
This article examines the complete ATP Masters 1000 title leaderboard, the records of Djokovic, Nadal and Federer, the Career Golden Masters, tournament-specific records and why Masters 1000 success matters in the debate over the greatest tennis player of all time.
Who Has the Most ATP Masters 1000 Titles? Quick Answer
Novak Djokovic holds the record with 40 ATP Masters 1000 titles.
The leading title winners are:
| Rank | Player | Masters 1000 Titles |
|---|---|---|
| 1 | Novak Djokovic | 40 |
| 2 | Rafael Nadal | 36 |
| 3 | Roger Federer | 28 |
| 4 | Andre Agassi | 17 |
| 5 | Andy Murray | 14 |
| 6 | Pete Sampras | 11 |
| 7 | Jannik Sinner | 10 |
The top three immediately stand out.
Djokovic — 40
Nadal — 36
Federer — 28
Together, the Big Three won an extraordinary 104 ATP Masters 1000 titles.
Their dominance at this level is another major reason their era occupies such an important place in tennis history.
What Is an ATP Masters 1000 Tournament?
ATP Masters 1000 tournaments are among the most prestigious events on the men’s professional tennis calendar.
The Masters series began in 1990, although its name and branding have changed over time.
Today, Masters 1000 events sit immediately below the Grand Slam tournaments and ATP Finals in the structure of elite men’s tennis.
The “1000” refers to the number of ranking points traditionally awarded to the singles champion.
Because these tournaments regularly attract the best players in the world, winning a Masters 1000 title is one of the biggest achievements available on the ATP Tour.
Winning 10 is exceptional.
Winning 20 is extremely rare.
Reaching 30 has been achieved by only two players.
And only one man has reached 40.
Novak Djokovic — 40 ATP Masters 1000 Titles
The All-Time Record Holder
Novak Djokovic holds the record with 40 Masters 1000 championships.
His first Masters 1000 title came in Miami in 2007.
Over the following years, Djokovic accumulated titles across hard courts and clay while competing directly against Roger Federer, Rafael Nadal, Andy Murray and later generations of elite players.
His 40th Masters 1000 championship established a benchmark no other man has reached.
But the total of 40 is only one part of Djokovic’s Masters résumé.
His greatest achievement at this level may be his success across every current Masters 1000 tournament.

Djokovic’s ATP Masters 1000 Titles by Tournament
Djokovic has won every current Masters 1000 event.
His title distribution is:
| Tournament | Djokovic Titles |
|---|---|
| Indian Wells | 5 |
| Miami | 6 |
| Monte-Carlo | 2 |
| Madrid | 3 |
| Rome | 6 |
| Canada | 4 |
| Cincinnati | 3 |
| Shanghai | 4 |
| Paris | 7 |
| Total | 40 |
This distribution reveals something important.
Djokovic did not build his record by dominating only one or two tournaments.
He won throughout the Masters calendar.
He succeeded in North America.
He succeeded in Europe.
He succeeded in Asia.
He won on hard courts.
He won on clay.
And he won every current Masters 1000 event at least twice.
What Is the Career Golden Masters?
The Career Golden Masters means winning all nine current ATP Masters 1000 tournaments at least once.
For years, even the greatest players struggled to complete the set.
Different tournaments favor different playing styles.
Clay specialists may struggle at faster hard-court events.
Hard-court specialists may struggle at Monte-Carlo or Rome.
Conditions change dramatically throughout the season.
That is why completing the entire collection represents extraordinary versatility.
Djokovic’s Historic Career Golden Masters
The First Man to Win All Nine
In 2018, Djokovic won Cincinnati and completed the Career Golden Masters.
He had now won all nine current Masters 1000 tournaments:
Indian Wells
Miami
Monte-Carlo
Madrid
Rome
Canada
Cincinnati
Shanghai
Paris
No player had previously completed the full set under the current nine-event structure.
But Djokovic went further.
The Double Career Golden Masters
By winning Monte-Carlo for a second time in 2020, Djokovic completed something even more remarkable.
He had now won every current Masters 1000 tournament at least twice.
The Double Career Golden Masters demonstrated not merely the ability to win everywhere once, but to repeatedly succeed across the entire Masters calendar.
It remains one of the strongest demonstrations of all-surface and all-condition versatility in men’s tennis.
Jannik Sinner and the Career Golden Masters
In 2026, Jannik Sinner joined one of the most exclusive clubs in Masters 1000 history.
By completing the set of all nine current tournaments, Sinner achieved the Career Golden Masters.
He became only the second player to accomplish the feat under the current nine-tournament structure after Djokovic.
Sinner reached the milestone with his 10th Masters 1000 title.
That achievement is particularly significant because it demonstrates how difficult winning across the complete Masters calendar remains even for elite champions.
Djokovic, however, remains unique in having completed the set twice.
Rafael Nadal — 36 ATP Masters 1000 Titles
Rafael Nadal ranks second with 36 Masters 1000 championships.
As with his Grand Slam career, Nadal’s Masters résumé was heavily shaped by his extraordinary clay-court dominance.
He won 26 clay-court Masters 1000 titles.
That total alone would place him among the most successful Masters players in history.
Nadal’s Clay Masters Dominance
Nadal’s major Masters records include:
Monte-Carlo — 11 titles
Rome — 10 titles
Madrid — 5 titles
His 11 Monte-Carlo championships represent one of the most extraordinary tournament records in ATP history.
Nadal’s dominance at clay Masters events mirrored his unprecedented success at Roland Garros.
But his 36 titles were not limited to clay.
He also won major Masters championships on hard courts, demonstrating that his success extended beyond his strongest surface.
For his complete career and records, visit our Rafael Nadal profile.
Roger Federer — 28 ATP Masters 1000 Titles
Roger Federer ranks third with 28 Masters 1000 championships.
Federer’s Masters success was particularly strong on hard courts.
Among his most notable tournament achievements was his record at Cincinnati.
Federer at Cincinnati
Federer won Cincinnati seven times.
That remains the tournament record.
His combination of serve, aggressive baseline play and ability to shorten points made the conditions particularly suitable for his game.
Federer also won Indian Wells five times.
While he did not complete the Career Golden Masters, he won eight of the nine current Masters 1000 tournaments during his career.
His Masters résumé forms an important part of his overall GOAT case.
Explore his complete career in our Roger Federer profile.
Djokovic vs Nadal vs Federer: Masters 1000 Titles
The Big Three comparison is:
| Player | Masters 1000 Titles |
|---|---|
| Novak Djokovic | 40 |
| Rafael Nadal | 36 |
| Roger Federer | 28 |
Djokovic leads Nadal by four titles.
He leads Federer by 12.
But the numbers become even more interesting when Grand Slam titles and rankings are added.
| Player | Grand Slams | Masters 1000 Titles | Weeks at No. 1 |
|---|---|---|---|
| Novak Djokovic | 24 | 40 | 428 |
| Rafael Nadal | 22 | 36 | 209 |
| Roger Federer | 20 | 28 | 310 |
Djokovic leads the Big Three in Grand Slam titles, Masters 1000 titles and total weeks at World No. 1.
Nadal ranks second in Grand Slams and Masters titles.
Federer ranks second in weeks at No. 1.
These differences are why comparing greatness requires more than looking at a single statistic.
Read our complete Djokovic vs Nadal vs Federer comparison for the broader picture.
Andre Agassi — 17 ATP Masters 1000 Titles
Andre Agassi won 17 Masters 1000 titles, placing him fourth among the leading champions of the Masters era.
Agassi’s success is particularly important historically because much of it came before Federer, Nadal and Djokovic transformed the record book.
He was one of the dominant hard-court players of his generation.
Agassi also won all four Grand Slam tournaments during his career, making him one of the relatively small number of men’s players to complete the Career Grand Slam.
His Masters record demonstrates the depth of his success outside the majors.
Andy Murray — 14 ATP Masters 1000 Titles
Andy Murray won 14 Masters 1000 championships.
His total becomes even more impressive when we consider his era.
Murray competed directly against Federer, Nadal and Djokovic during much of his prime.
Those three players collectively won more than 100 Masters titles.
Yet Murray still managed to win 14 himself.
His Masters success was one of the major reasons he reached World No. 1 and established himself as the leading challenger to the Big Three.
Murray’s career demonstrates just how difficult it was for other elite players to win major tournaments during that period.
Pete Sampras — 11 ATP Masters 1000 Titles
Pete Sampras won 11 Masters 1000 titles.
Sampras played during the earlier years of the Masters series, which began in 1990.
His greatest achievements are often associated with his 14 Grand Slam championships, seven Wimbledon titles and years at World No. 1.
But his Masters record provides additional evidence of his ability to consistently win major events outside the Grand Slams.
Jannik Sinner — 10 ATP Masters 1000 Titles
As of August 2026, Jannik Sinner has won 10 ATP Masters 1000 championships.
His rise through the Masters record book has been extremely fast.
More importantly, he has already won all nine current Masters 1000 tournaments.
That makes Sinner’s record about more than total volume.
It demonstrates extraordinary versatility across the complete Masters calendar.
Whether he can eventually challenge the totals of Federer, Nadal or Djokovic will depend on his ability to sustain this level for many more seasons.
But reaching 10 titles and completing the Career Golden Masters while still in his twenties puts him in historically significant territory.
Who Has Won the Most Clay-Court Masters 1000 Titles?
The answer is Rafael Nadal.
Nadal won 26 clay-court Masters 1000 titles.
That includes his extraordinary records at:
Monte-Carlo — 11
Rome — 10
Madrid — 5
His total demonstrates how thoroughly Nadal dominated the clay portion of the ATP calendar.
Djokovic ranks far behind Nadal in clay Masters titles despite being one of the greatest clay-court players of his generation.
That gap illustrates the scale of Nadal’s dominance on the surface.
Who Has Won the Most Monte-Carlo Masters Titles?
Rafael Nadal — 11 titles
Monte-Carlo became one of Nadal’s signature tournaments.
His 11 championships represent the tournament record.
Nadal’s ability to repeatedly dominate elite opposition on the slow clay courts of Monte-Carlo was a preview of the same qualities that made him almost unbeatable at Roland Garros.
Who Has Won the Most Rome Masters Titles?
Rafael Nadal — 10 titles
Nadal holds the Rome record with 10 championships.
Djokovic is second among the modern leaders with six.
The Rome Masters became one of the most important battlegrounds in the Djokovic-Nadal rivalry because both players were exceptional on the surface.
Their clay-court battles provide important context for Nadal’s and Djokovic’s Masters totals.
Read our complete Novak Djokovic vs Rafael Nadal head-to-head.
Who Has Won the Most Cincinnati Masters Titles?
Roger Federer — 7 titles
Cincinnati was one of Federer’s most successful Masters tournaments.
His aggressive style and ability to dominate shorter points translated exceptionally well to the conditions.
Federer’s seven championships remain the tournament record.
Who Has Won the Most Paris Masters Titles?
Novak Djokovic — 7 titles
Djokovic holds the Paris Masters record with seven championships.
His success in Paris contributed significantly to his overall total of 40 Masters 1000 titles.
It also demonstrates his exceptional indoor hard-court ability.
Who Has Won the Most Miami Masters Titles?
The leading total is six titles.
Andre Agassi and Novak Djokovic have each won Miami six times.
Miami played an important role in Djokovic’s early development into one of the world’s best players.
His first Masters 1000 championship came there in 2007.
Who Has Won the Most Indian Wells Masters Titles?
The men’s record is shared.
Novak Djokovic — 5
Roger Federer — 5
Indian Wells has often been described as one of the most prestigious tournaments outside the Grand Slams.
Both Djokovic and Federer produced exceptional records there.
Which Player Has Won the Most Different Masters 1000 Events?
Novak Djokovic has won all nine current Masters 1000 tournaments.
More importantly, he has won all nine at least twice.
Jannik Sinner has also won all nine current events, completing his first Career Golden Masters in 2026.
Roger Federer won eight of the nine.
Rafael Nadal won seven of the nine.
This category measures something different from total titles.
It measures breadth.
A player might dominate a small number of events and accumulate many championships.
Winning every tournament requires success under a much wider range of conditions.
Why Federer Never Completed the Career Golden Masters
Federer won eight of the nine current Masters 1000 tournaments.
The one missing tournament was Monte-Carlo.
He reached the final multiple times but never won the championship.
That is not particularly surprising given the competition.
Federer’s prime overlapped with Rafael Nadal’s unprecedented clay-court dominance.
Monte-Carlo was one of Nadal’s greatest tournaments.
This provides another example of why historical statistics require context.
A missing title doesn’t necessarily mean a player lacked the ability to win the tournament.
Sometimes another all-time great stood in the way.
Why Nadal Never Completed the Career Golden Masters
Nadal won seven of the nine current Masters tournaments.
The two missing events were:
Miami
Paris
Nadal reached multiple Miami finals but never won the title.
Paris also remained absent from his résumé.
Despite those gaps, Nadal still accumulated 36 Masters championships — the second-highest total in history.
His record was built primarily through extraordinary dominance at clay events combined with significant success elsewhere.
The Big Three Won 104 Masters 1000 Titles
Consider this number:
104.
That is the combined number of Masters 1000 titles won by Djokovic, Nadal and Federer.
Djokovic — 40
Nadal — 36
Federer — 28
Their dominance at Grand Slam tournaments is well known.
But their Masters dominance may be just as important for understanding their era.
Masters events occur throughout the season.
They take place on different surfaces.
They involve different conditions.
And they regularly feature elite fields.
Winning 104 of them demonstrates that the Big Three did not merely dominate four tournaments per year.
They dominated the entire structure of elite men’s tennis.
Djokovic’s Historic 2015 Masters Season
One of the most extraordinary Masters 1000 seasons came from Novak Djokovic in 2015.
He won six Masters 1000 titles in a single season.
That remains the record.
The achievement becomes even more impressive when placed alongside the rest of Djokovic’s 2015 season, which included three Grand Slam championships and one of the greatest overall seasons in men’s tennis history.
Winning six Masters events in one year demonstrates an extraordinary level of sustained dominance.
It required Djokovic to repeatedly beat elite fields across different tournaments and conditions throughout the season.
Masters 1000 Titles vs Grand Slam Titles
Which achievement matters more?
Grand Slam titles generally carry greater historical importance.
They are tennis’s biggest tournaments.
But Masters titles provide information that Grand Slam totals alone cannot.
Grand Slams measure performance at four tournaments.
Masters 1000 events measure elite performance across a much broader portion of the season.
Compare the Big Three:
| Player | Grand Slam Titles | Masters 1000 Titles |
|---|---|---|
| Novak Djokovic | 24 | 40 |
| Rafael Nadal | 22 | 36 |
| Roger Federer | 20 | 28 |
The same three players dominate both categories.
That is important.
It suggests their Grand Slam success was not isolated.
They were also consistently winning the next-highest tier of major ATP tournaments.

Masters 1000 Titles vs Weeks at World No. 1
Masters titles and rankings are closely connected.
Deep runs at Masters 1000 tournaments generate significant ranking points.
Consistently winning them can therefore play an important role in reaching and maintaining the No. 1 ranking.
The Big Three comparison shows:
| Player | Masters 1000 Titles | Weeks at No. 1 |
|---|---|---|
| Novak Djokovic | 40 | 428 |
| Rafael Nadal | 36 | 209 |
| Roger Federer | 28 | 310 |
Once again, the statistics measure different forms of success.
Masters titles measure tournament victories.
Weeks at No. 1 measure sustained ranking dominance.

Why Masters 1000 Titles Matter in the GOAT Debate
Grand Slam titles deserve enormous weight in GOAT discussions.
But imagine evaluating an entire tennis career using only four tournaments per season.
That would leave out a huge amount of elite competition.
Masters 1000 tournaments help fill that gap.
They reveal:
- Consistency outside the majors
- Success across different parts of the season
- Surface versatility
- Ability to repeatedly defeat elite opponents
- Longevity
- Week-to-week dominance
This is why Djokovic’s record of 40 matters.
It supports his Grand Slam and ranking records with another major category of sustained success.
But Masters titles should still be considered as one component of a broader evaluation.
Our guide to how the greatest tennis player of all time is determined examines the different criteria that can be used.
Djokovic’s Masters Record and the GOAT Debate
Djokovic’s statistical case is unusually broad.
He holds:
24 Grand Slam singles titles
40 ATP Masters 1000 titles
428 weeks at World No. 1
He also completed the Double Career Golden Masters.
Each achievement measures something different.
Grand Slams measure success on the biggest stages.
Masters titles measure elite success across the regular tour.
Weeks at No. 1 measure sustained ranking dominance.
The fact that Djokovic leads all three categories among the Big Three gives his GOAT argument unusual statistical depth.
That does not mean every fan must consider him the greatest.
But any serious evaluation of his career has to account for the breadth of those records.
Nadal’s Masters Record and the GOAT Debate
Nadal’s 36 Masters championships reinforce the central theme of his career:
extraordinary clay-court dominance combined with elite all-surface success.
His 26 clay Masters titles are unmatched.
Combined with his 14 Roland Garros championships, they create a level of dominance on one surface that may never be repeated.
Nadal’s Masters résumé therefore strengthens one of the most powerful arguments in his GOAT case:
No leading men’s player dominated a single surface as completely as Nadal dominated clay.
Federer’s Masters Record and the GOAT Debate
Federer’s 28 Masters titles are lower than Djokovic’s and Nadal’s totals.
But his record still demonstrates remarkable longevity and versatility.
He won eight of the nine current Masters tournaments.
He holds the Cincinnati record with seven titles.
He shares the Indian Wells record with Djokovic.
And many of his Masters seasons occurred while competing directly against Nadal and Djokovic.
Federer’s Masters record should therefore be evaluated alongside his 20 Grand Slams, 310 weeks at No. 1 and record 237 consecutive weeks at No. 1.
The Big Three Masters Rivalries
The Masters tournaments provided many of the most important meetings between Djokovic, Nadal and Federer.
These matches frequently influenced:
- Tournament titles
- Ranking positions
- Season momentum
- The historical balance between the three players
Their direct rivalries help explain how difficult accumulating 28, 36 or 40 Masters championships really was.

Could Anyone Break Djokovic’s 40 Masters 1000 Titles Record?
Yes.
But 40 is an enormous target.
To understand the scale:
Nadal finished with 36.
Federer finished with 28.
Agassi won 17.
Murray won 14.
Sampras won 11.
Reaching 40 requires more than a few dominant seasons.
A player must repeatedly win elite tournaments over a long career.
Jannik Sinner has already reached 10 and completed the Career Golden Masters.
Other current and future champions may continue climbing the leaderboard.
But getting from 10 to 40 would require another 30 championships.
That illustrates just how high Djokovic has set the standard.

Novak Djokovic — 40
Rafael Nadal — 36
Roger Federer — 28
Andre Agassi — 17
Andy Murray — 14
Pete Sampras — 11
Jannik Sinner — 10

They also occupy the top three positions in men’s Grand Slam singles titles.
And Djokovic and Federer occupy the top two positions in total weeks at World No. 1.
The overlap demonstrates just how completely the Big Three dominated modern men’s tennis.
But it also gives us another way to evaluate their greatness.
Grand Slams tell us who won the biggest tournaments.
Rankings tell us who stayed on top the longest.
Masters titles tell us who repeatedly dominated elite competition throughout the regular tour.
A complete GOAT argument should consider all three.

Novak Djokovic — 40
Rafael Nadal — 36
Roger Federer — 28
Andre Agassi — 17
Andy Murray — 14
Pete Sampras — 11
Jannik Sinner — 10
Djokovic also became the first player to win all nine current Masters tournaments and the first to win every one at least twice.
Nadal owns the record for clay Masters dominance.
Federer holds major individual tournament records of his own.
And Sinner has joined the Career Golden Masters club in 2026.
Masters 1000 titles are not the only measure of tennis greatness.
But they reveal something Grand Slam totals alone cannot:
who repeatedly dominated elite competition throughout the entire ATP season.
And by that measure, 40 is the number at the top.
