Joe Salisbury (/ˈsɔːlzbəri, ˈsɒlz-/ SAWLZ-bər-ee, SOLZ-; born 20 April 1992) is a British professional tennis player who is a former world No. 1 in doubles.

He is a six-time Grand Slam champion, having won the 2020 Australian Open and the 2021, 2022 and 2023 US Opens in men's doubles with Rajeev Ram, as well as the 2021 French and US Opens in mixed doubles alongside Desirae Krawczyk. Salisbury also finished runner-up at the 2021 Australian Open in men's doubles and the 2021 Wimbledon Championships in mixed doubles, with Ram and Harriet Dart respectively. In April 2022, Salisbury became the third British world No. 1 in either singles or doubles, after Jamie and Andy Murray. He has won 17 doubles titles on the ATP Tour, including the 2022 and 2023 ATP Finals and three at Masters 1000 level.

Salisbury made his Davis Cup debut for Great Britain in 2021 and also competed at the 2020 Summer Olympics alongside Andy Murray.

Salisbury is from Putney in southwest London. He went to King's College School, Wimbledon, leaving in 2010. He trained at the Sutton Tennis Centre under Jeremy Bates and played college tennis at the University of Memphis.

Salisbury represented the Memphis Tigers from 2010 until his graduation in 2014. As he had experienced injury problems during his junior career he was not heavily recruited by American colleges and the decision to offer him a spot at Memphis was a "gamble" on the part of head coach Paul Goebel.

Salisbury finished his college career with 97 doubles wins with his partner David O’Hare, the most in school history, and his 25 singles wins in his final year was also a Memphis record at the time.

Salisbury made his ATP Tour main-draw debut at the U.S. National Indoor Championships partnering David O'Hare, losing to the Bryan brothers in the first round.

He reached the semifinals in the Wimbledon men's doubles with Frederik Nielsen.
