The 2021 US Open was the 141st edition of the tournament and took place at the
USTA Billie Jean King National Tennis Center in
Flushing Meadows–Corona Park of
Queens in New York City, United States. The tournament was an event run by the
International Tennis Federation (ITF) and part of the
2021 ATP Tour and the
2021 WTA Tour calendars under the Grand Slam category. The tournament consisted of both men's and women's singles and doubles draws, as both doubles draws returned to the standard 64 players, and singles players remained in standard 128-person format in each category. There were also singles and doubles events for both boys and girls (players under 18). The tournament was played on hard courts and took place over a series of 17 courts with
Laykold surface, including the three existing main showcourts—
Arthur Ashe Stadium,
Louis Armstrong Stadium and
Grandstand. Wheelchair events were held on September 9 as scheduled. Unlike previous events on scheduling conflicts with the tournament and the
Summer Paralympic Games, the
2020 Summer Paralympics (which was delayed from 2020 due to the pandemic) were held during the first week of the tournament. == Singles players ==
