Mark Leo Turgeon (born February 5, 1965) is an American college basketball coach. He is currently the head coach for the University of Maryland Terrapins. Turgeon previously served as head coach at Texas A&M for 4 years.

Mark Turgeon was born and raised as one of five children in Topeka, Kansas. After graduating from Hayden High School, Turgeon attended the University of Kansas, where he earned a bachelor's degree in Personnel Administration in 1987. He added a master's degree in Education from the University of Oklahoma in the same year. He is married to the former Ann Fowler, whom he met at KU, and together they have three children.

Turgeon played basketball at Hayden High School, helping the team post a 47-3 record and capture two consecutive Class 4A State Championships in 1982 and 1983. Turgeon earned All-State Tournament team honors in both of those years.

Although only 5 feet 10 inches out of high school, Turgeon earned a scholarship to play basketball at the University of Kansas under Coach Larry Brown. Turgeon played in four straight NCAA tournaments, becoming the first KU player to do so. He was a reserve point guard for the 1985–86 Jayhawk team that won the Big Eight Conference regular season and tournament title and also advanced to the Final Four in the 1986 NCAA Men's Division I Basketball Tournament. The team finished that season 35–4 overall. Turgeon was a team captain for both the 1986 and 1987 squads, a member of the Big Eight All-Freshmen Team in 1984, and was also a Big Eight All-Academic Performer in 1986. Fans called him "The Surgeon" because, in addition to the phrase rhyming with his surname, he had the ability to "carve up defenses."
