What is Djokovic's record number of weeks as world No. 1? The answer is 428 weeks. That is the all-time record for the ATP men's singles rankings, a mark Djokovic built across several separate periods at the top rather than in one uninterrupted streak.
Djokovic first became world No. 1 on July 4, 2011, after winning Wimbledon. His longest individual reign lasted 122 weeks, from July 2014 to November 2016. He returned to No. 1 several times, including in 2018, 2020, 2021, 2022, 2023, and 2024.
The total-weeks record is different from the consecutive-weeks record. Roger Federer holds the consecutive record at 237 weeks, while Djokovic's 428 counts every week he occupied the top position. Djokovic also holds records for eight year-end No. 1 finishes and for ranking No. 1 in 13 different years.
The ATP ranking is calculated weekly from tournament results, so the figure is a career total that can be compared across different eras.
