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 to 14, 2015.

The tournament included fourteen of the fifteen ACC teams, as Syracuse did not compete due to a self-imposed postseason ban.

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).
