Ranking the tennis greats who spent the most weeks at World No. 1

9. Jannik Sinner (69 weeks)

Sinner edges Alcaraz by just three weeks on this list, having held the No. 1 ranking for 69 weeks as of April 2026, and the gap between them is likely to keep shifting throughout the year. The Italian reached the top spot in 2024 and has held it with the kind of calm, methodical consistency that is unusual for a player so early in his career. He won the Australian Open in 2024 and 2025 and the US Open in 2024, and his clay court form heading into the 2026 French Open suggests the weeks will keep coming. Both he and Alcaraz are at the very beginning of what could become historic careers on this list.

8. Stefan Edberg (72 weeks)

Edberg was the finest serve-and-volley player of the 1980s and early 1990s, a graceful and technically immaculate Swede who reached No. 1 in 1990 and held the ranking for 72 weeks. He won six Grand Slams and was widely considered one of the most complete players of his era, comfortable on all surfaces and capable of beating anyone on his best day. His career overlapped almost entirely with those of Ivan Lendl, Boris Becker, and McEnroe, limiting his time at the top despite a level of consistent excellence that would have produced more weeks in virtually any other era.

7. Lleyton Hewitt (80 weeks)

Hewitt became the youngest world No. 1 in ATP history when he reached the top spot in 2001 at the age of 20, a record that stood until Alcaraz broke it two decades later. He won the US Open in 2001 and Wimbledon in 2002 and played with a ferocity and defensive intensity that wore opponents down over long matches. His time at the top was relatively brief by the standards of this list, but the manner in which he got there and held it, through sheer competitive will rather than overpowering physical gifts, made him one of the most admired players of his generation.

6. John McEnroe (170 weeks)

McEnroe was one of the most gifted tennis players who ever lived, a left-handed serve-and-volleyer with touch and creativity that no one else in his generation could match. He reached No. 1 for the first time in 1980 and held it across multiple separate stints throughout the early 1980s, finishing the year as the top-ranked player four times. His 170 weeks at the top sit sixth on the all-time list, a number that undersells how dominant he was at his absolute peak, given that he spent much of his prime competing directly with Jimmy Connors and Ivan Lendl, two of the other names higher on this list.

5. Rafael Nadal (209 weeks)

Nadal spent 209 weeks at world No. 1 across his career, finishing the year in the top spot five times. By Grand Slam titles, he is one of the greatest players in history with 22 majors, but his weeks-at-No. 1 figure reflects the era he competed in, sandwiched between Federer’s dominant run and Djokovic’s historic one, and dealing with injuries that repeatedly disrupted his time at the top. On clay, he was essentially unbeatable for the better part of two decades. Across the full calendar, he was magnificent but not consistently dominant enough to accumulate the kind of uninterrupted weeks at No. 1 that the players above him on this list managed.

4. Jimmy Connors (268 weeks)

Connors was the first player in the ATP ranking era to truly dominate the No. 1 spot, reaching the top on July 29, 1974 and holding it for 160 consecutive weeks, a record that stood for over 30 years until Roger Federer broke it. He finished the year as No. 1 five times in a row from 1974 through 1978, and returned to the top spot again in 1982 and 1983. His total of 268 weeks makes him fourth on the all-time list, and his influence on what sustained No. 1 dominance could look like in the ranking era was foundational. Every player who came after him and chased the record was in some way chasing what Connors built first.

3. Ivan Lendl (270 weeks)

Lendl spent 270 weeks at world No. 1 and finished the year in the top spot five times between 1985 and 1989, one of the most sustained runs of year-end dominance the sport has seen. He was a relentless, disciplined competitor who transformed professional tennis training and preparation, shaping how the sport approached fitness for decades afterward. He won eight Grand Slams and reached 19 finals, and his baseline game was the template that most of the players who followed him built upon. His 270-week edge over Connors by just two, making their rivalry at the top of the rankings one of the tightest in the sport’s history.

2. Pete Sampras (286 weeks)

Sampras held the year-end No. 1 ranking for six consecutive years from 1993 through 1998, a record that has never been matched. His 286 total weeks at No. 1 place him second on the all-time list among non-Big Three players, and the consistency he produced across that stretch of the 1990s is one of the great sustained achievements in tennis history. He won 14 Grand Slams, dominated Wimbledon and the US Open with a serve-and-volley game that nobody could consistently handle, and finished every year at the top of the sport for half a decade in a row. He retired in 2002 as the most decorated Grand Slam champion in men’s tennis history, a record that held until Federer surpassed him in 2009.

1. Novak Djokovic (428 weeks)

The number alone tells the story. Djokovic spent 428 weeks at world No. 1, more than any player in ATP history by a margin of 118 weeks over the second-place Roger Federer, who spent 310 weeks at the top himself. He finished the year as No. 1 eight times, also a record, and his dominance across the 2010s and early 2020s was unlike anything men’s tennis had seen before. He won 24 Grand Slams, the most in men’s tennis history, across all four surfaces, in multiple separate peaks spanning over 15 years. His 428 weeks represent over eight years at the very top of the sport, and no active player is remotely close. The gap between Djokovic and Federer in second place is 118 weeks, more than two full years. The gap between Federer and Sampras is 24 weeks. The further down this list you go, the tighter the numbers get. At the top, Djokovic sits alone in a category he built himself, through relentless excellence across an era that also contained Federer and Nadal, two players who would have dominated any other generation in the sport’s history. The weeks-at-No. 1 record is the most honest measure of sustained greatness the sport produces, and by that measure, the answer is not a debate.

The ten players on this list, from McEnroe’s 170 weeks to Djokovic’s 428, collectively represent the backbone of men’s tennis across five decades. Carlos Alcaraz and Jannik Sinner are currently trading the No. 1 ranking back and forth in what is shaping up to be the next great rivalry in the sport, with Sinner holding 69 weeks and Alcaraz 66 as of April 2026. They have a very long way to go. But they are the ones watching this list now and deciding whether chasing it is something they believe they can do.
