The longest uninterrupted spell at No. 1 in men’s tennis is Roger Federer’s 237 weeks. On the women’s side, Steffi Graf and Serena Williams share the record, with 186 weeks each. Those streaks are measured on the official singles rankings—not by how many tournaments a player won in a row—and they show just how long a champion can stay ahead of the field.
The records at a glance
| Tour | Player | Consecutive weeks at No. 1 | Streak |
|---|---|---|---|
| ATP | Roger Federer | 237 | February 2, 2004–August 17, 2008 |
| WTA | Steffi Graf | 186 | August 17, 1987–March 10, 1991 |
| WTA | Serena Williams | 186 | September 8, 2014–November 6, 2016 |
The ATP and WTA keep separate rankings, so there isn’t one combined men’s-and-women’s No. 1 record. Federer holds the men’s mark; Graf and Williams are joint record-holders on the women’s tour. The ATP rankings began in 1973 and the WTA rankings in 1975, so these records cover the modern official ranking eras.
How a consecutive-week streak works
Rankings are updated regularly, usually each week. A player’s streak continues as long as they remain at No. 1 on each successive ranking, whether they played a tournament that week or not. It’s therefore different from winning a run of tournaments: a player can lose a final, skip an event or take a break and still keep the top ranking.
In both the ATP and WTA singles rankings, results earn points over a rolling period, generally based on the previous 52 weeks. As old results drop off, players need strong new results to maintain their totals. A leading player may have a useful cushion, but the ranking can change quickly if a rival wins major events while the leader misses time or has points to defend.
That’s why the record is not simply a measure of how many trophies someone won. It reflects sustained results across a full schedule, and the ability to stay ahead of rivals as the ranking points shift week by week.
Federer’s 237-week run
Federer’s streak began on February 2, 2004, and lasted until August 17, 2008. For more than four and a half years, every new ATP singles ranking listed him at the top. His run came during a period of extraordinary consistency: he won Grand Slam titles on hard courts and grass, reached major finals on clay and repeatedly produced deep runs at the biggest events.
The length of the streak is especially striking because the competition at the top was not static. Rafael Nadal became a major threat, particularly on clay, and eventually took over No. 1 in August 2008 after winning the gold medal at the Beijing Olympics. Federer’s run ended, but he continued to compete at the highest level and later returned to the top of the rankings.
Federer’s record is not the same as the record for total time at No. 1. Novak Djokovic has accumulated more total weeks at the top of the ATP rankings, but his time there has been divided into separate spells. A long overall total and an uninterrupted streak measure two different kinds of achievement.
Graf and Williams share the WTA record
Steffi Graf: 186 consecutive weeks
Graf held the WTA No. 1 ranking for 186 straight weeks, from August 1987 to March 1991. The streak covered some of the most dominant tennis of her career. In 1988, she won all four Grand Slam singles titles and Olympic gold—a combination known as the Golden Slam. Her game paired forceful groundstrokes with exceptional movement, allowing her to attack while still defending remarkably well.
Graf’s streak ended when Monica Seles rose to No. 1. That handover marked the arrival of a serious new challenger at the top, rather than a sudden loss of Graf’s place in tennis history. She would go on to win further major titles and later have another spell as the world’s top-ranked player.
Serena Williams: 186 consecutive weeks
Williams matched Graf’s record with a run from September 2014 to November 2016. She won major titles during the streak, including the Australian Open, French Open and Wimbledon in 2015, and Wimbledon again in 2016. Her powerful serve and aggressive first-strike tennis could shorten points, while her movement and competitive focus helped her handle the pressure when matches tightened.
Williams’ streak ended when Angelique Kerber moved into the top spot in November 2016. Matching Graf’s 186 weeks was a remarkable feat in its own right: it required Williams to remain the ranking leader through multiple seasons, changing schedules and a deep field of challengers.
Consecutive weeks versus total weeks
These records are easy to mix up. Consecutive weeks count the longest unbroken stretch at No. 1. Total weeks add together every week a player has held the top spot, including separate spells with gaps in between.
For example, a player could spend 100 weeks at No. 1, drop behind a rival, then return for another 100. That would amount to 200 total weeks, but the longest consecutive run would still be only 100. Federer’s 237-week mark is about one uninterrupted stretch; Djokovic’s ATP total of 428 weeks, reached in March 2024, is a different record. On the WTA side, Graf holds the total-weeks record as well as sharing the consecutive-weeks mark.
Frequently Asked Questions
Who has spent the most consecutive weeks at No. 1 in men’s tennis?
Roger Federer holds the ATP singles record with 237 consecutive weeks, from February 2, 2004, to August 17, 2008.
Who has spent the most consecutive weeks at No. 1 in women’s tennis?
Steffi Graf and Serena Williams share the WTA singles record. Each spent 186 consecutive weeks at No. 1.
Does a player need to win every week to keep a No. 1 streak going?
No. The streak tracks the weekly ranking, not tournament wins. A player can lose a match or take a week off and remain No. 1 if their ranking points still put them ahead of the field.
Is the consecutive-weeks record the same as the total-weeks record?
No. Consecutive weeks measure the longest uninterrupted run, while total weeks add every spell at No. 1. A player can have a higher total without holding the longest single streak.
Final Thoughts
Federer’s 237 weeks remain the benchmark for an uninterrupted run at the top of the ATP rankings. In the WTA, Graf and Williams stand level at 186 weeks, reached in very different eras and through different paths. The numbers tell a clear story: staying No. 1 for even one season is difficult; holding that position for years takes rare consistency, resilience and the ability to keep answering the next challenger.
