Rafael Nadal spent 209 weeks ranked world No. 1 in men’s singles.
The Association of Tennis Professionals first placed Nadal at No. 1 on 18 August 2008, after his victory at Wimbledon and Olympic success. Across five separate periods at the top, he accumulated 209 weeks in total, placing him among the longest-serving No. 1 players in tennis history.
Nadal also finished five seasons as year-end No. 1: 2008, 2010, 2013, 2017 and 2019. His first reign lasted 46 weeks, while his longest continuous spell lasted 56 weeks. He returned to the top several times despite major injuries, including knee and abdominal problems.
The figure is often confused with Nadal’s 387 weeks at No. 2 or his 596 combined weeks in the top two. Those are different ranking totals. The 209-week figure refers specifically to weeks occupying the No. 1 position, not consecutive weeks and not total time inside the top 10.
