Patrick Kelsey (born May 15, 1975) is an American college basketball coach. He is the current head men's basketball coach at the University of Louisville. He previously served as head coach for the College of Charleston and Winthrop University.

Kelsey played high school basketball at Roger Bacon High School in Cincinnati, Ohio. He transferred to Elder High School for his senior year and in 1993 helped lead the team to a Division I state title. Kelsey began his collegiate career as a freshman guard at the University of Wyoming. He transferred to Xavier in 1994 where he played three seasons.

Kelsey began his career as an assistant coach at Wake Forest University and later Xavier University. During his time as an assistant coach, his teams earned an ACC regular season championship, five NCAA Tournament berths, an NIT berth, and a No. 1 national ranking in two different seasons. In 2010, College Bound Hoops ranked Kelsey eighth in the nation among college basketball assistants. Chris Mack, former A-10 and Big East Championship head coach, considered him to be one of the best assistant coaches in America.

As an assistant at Wake Forest, Kelsey coached a number of players who went on to have successful professional basketball careers, including NBA All-Stars Chris Paul and Jeff Teague. He coached Ish Smith, an All-ACC selection and player for the Houston Rockets, James Johnson, a two-time All-ACC selection and 17th overall draft pick by the Chicago Bulls in the 2009 NBA Draft, and Al-Farouq Aminu, a McDonald's All-America who was drafted eighth overall by the L.A. Clippers in the 2010 NBA Draft.

As head coach at Winthrop University, Kelsey resurrected a winning tradition and became one of the winningest coaches in the history of the Big South Conference (ranked 2nd all-time with 110 conference wins). During his nine seasons, no other Big South program had more conference wins or wins overall. The program made four straight Big South Conference tournament title games (2014–17) and the Eagles claimed the 2017, 2020, and 2021 Big South Conference Championships. The 2016–17 Eagles claimed a share of the Big South regular season championship and defeated the Campbell Fighting Camels in the title game to earn Winthrop’s 10th trip to the NCAA Tournament.

In 2017, Kelsey was hired as the head coach at Massachusetts, but returned to Winthrop two days after accepting the position, citing personal reasons. Kelsey informed UMass Athletic Director Ryan Bamford of his decision 25 minutes before the scheduled press conference to formally introduce Kelsey to the press and university community. Two days prior, Kelsey had signed an MoU with the university, which included a $1 million buyout clause should Kelsey leave before two years.

Kelsey's 2019–20 Eagles team secured the Big South regular season championship and defeated the Hampton Pirates in the conference championship game to earn what would have been Winthrop's 11th trip to the NCAA tournament. However, the 2020 NCAA tournament was canceled due to the COVID-19 pandemic. The 2020–21 Eagles started the season 16–0 and had a cumulative 21-game winning streak dating back to the prior season, which were both program records. They defeated Campbell in the conference tournament to earn their 11th NCAA Tournament bid. Following the season, Kelsey was named a finalist for the Jim Phelan Award (national coach of the year) and the Skip Prosser Man of the Year Award.

Under Kelsey, the program broke multiple school records and produced some of the best players in its history, including Keon Johnson, Winthrop's all-time leading scorer, and Xavier Cooks, Winthrop's all time leading rebounder and shot-blocker.
