2021 US Open – Men's Singles

Daniil Medvedev defeated Novak Djokovic in the final, 6–4, 6–4, 6–4 to win the men's singles tennis title at the 2021 US Open. It was his first major title and he only lost one set en route (against Botic van de Zandschulp in the quarterfinals). Medvedev became the third Russian man, after Yevgeny Kafelnikov and Marat Safin, to win a major singles title, and the first to do so since Safin at the 2005 Australian Open.

Dominic Thiem was the reigning champion, but did not participate due to an ongoing wrist injury.

Djokovic was aiming to become the second man in the Open Era, after Rod Laver in 1969, to complete a Grand Slam. He was also attempting to win an outright record 21st major singles title and surpass his Big Three counterparts, Roger Federer and Rafael Nadal. By reaching the final, Djokovic tied Federer's record of 31 men's singles major finals contested, and repeated his 2015 achievement of contesting the maximum-possible 28 major singles matches in a season. This marked Djokovic's record sixth runner-up finish at the event.

By defeating world No. 3 Stefanos Tsitsipas in the third round, Carlos Alcaraz became the youngest man to beat a top 3 ranked-player in singles at the US Open since the inception of the ATP rankings in 1973. He became the youngest male quarterfinalist at a singles major since Michael Chang at the 1989 French Open, and the youngest at the US Open in the Open Era; he would go on to win the title the following year. Van de Zandschulp became the first Dutchman to reach a singles major quarterfinal since Sjeng Schalken at the 2004 Wimbledon Championships and the first qualifier to do so at the US Open since Gilles Müller in 2008.
