Aisam-ul-Haq Qureshi (Urdu: اعصام الحق قریشی) (born March 17, 1980, in Lahore, Pakistan) is a professional tennis player from Pakistan. He is currently Pakistan's top player. A top 10 doubles player, his highest Singles Race ranking is 103rd and is the former Singles Asian No. 3 and Asian No. 2 in Doubles. He is the only Pakistani tennis player to reach the final of a Grand Slam, which he did in 2010 competing in both mixed doubles (partnering with Květa Peschke) and men's doubles (partnering with Rohan Bopanna) at the US Open.
Qureshi teamed with Israeli player Amir Hadad during Wimbledon and the US Open tournaments in 2002. The duo won the Arthur Ashe Humanitarian of the Year award for playing together despite pressure from their communities.
As Pakistani No. 1, Qureshi has traditionally led Pakistan's Davis Cup campaigns. After shocking New Zealand in the Asia/Oceania Zone Group I second round play-off in 2004 to survive relegation, he took them to the World Group Play-Offs for the first time in 2005, before they were beaten by Chile. He has won the most Davis Cup matches for Pakistan, being the most successful singles and doubles player ever. He is also half of the most successful doubles pairing for Pakistan (with Aqeel Khan) in the country's sporting history.
Qureshi is now a member of the "Champions for Peace" club, a group of 54 athletes committed to serving peace in the world through sport, created by Peace and Sport, a Monaco-based international organization.
Aisam and his partner Rohan Bopanna have created a campaign, Stop War Start Tennis, with their goal to play a match on the border joining India and Pakistan.
