ATP 500 tournaments
The ATP 500 tournaments are the fourth-highest tier of annual men's tennis tournaments, after the four Grand Slam tournaments, ATP Finals, and the ATP Masters 1000 events. The winners of each tournament are awarded 500 ranking points—which accounts for the name of the series.
As of 2025, the series includes 16 tournaments, which have draws of 32 for singles and 16 for doubles. Leading players must enter at least four 500 events, including at least one after the US Open; if they play fewer than four, or fail to play in one after the US Open they get a "zero" score towards their world ranking for each one short.
Roger Federer has won the most ATP 500 singles titles, while Daniel Nestor has won the most doubles titles.
