Who became the oldest Open Era US Open men's singles champion in 2023?

Novak Djokovic became the oldest Open Era US Open men’s singles champion by winning the 2023 title. He defeated Daniil Medvedev 6–3, 7–6, 6–3 in the final at age 36 years and 111 days.

The victory was Djokovic’s fourth US Open championship, following titles in 2011, 2015 and 2018. It also gave him a record-extending 24th men’s singles major title, tying Margaret Court’s all-time total of 24 major singles championships across the women’s and men’s games.

Djokovic’s record is specifically an Open Era distinction, covering professional tennis from 1968 onward. The achievement is often confused with the record for oldest US Open champion in any era, because earlier champions competed before the Open Era began. Roger Federer and Rafael Nadal were among Djokovic’s major-era contemporaries, but neither held this particular US Open age record. Djokovic beat Medvedev in a rematch of the 2021 US Open final, which Medvedev had won.
