2015 ACC men's basketball tournament

The 2015 Atlantic Coast Conference men's basketball tournament was the postseason men's basketball tournament for the Atlantic Coast Conference, held at the Greensboro Coliseum in Greensboro, North Carolina, from March 10–14, 2015. The tournament included fourteen of the fifteen ACC teams, as Syracuse did not compete due to a self-imposed postseason ban. Seeds 5 through 10 received a first-round bye, and the top four seeds received a "double bye" through the first round and second rounds. The 2015 tournament was the first to begin on a Tuesday and the first since 1981 to finish on a Saturday. The semifinals and championship game were played in the evening instead of their traditional afternoon timeslot. It was the fourth time a team has played 4 games (NC State in 1997 and 2007, Georgia Tech in 2010). ESPN and the ACC Network televised all games, and the championship game was moved to Saturday to facilitate a prime-time broadcast on ESPN.
