Atlantic Coast Conference men's basketball Coach of the Year

The Atlantic Coast Conference men's basketball Coach of the Year is a basketball award given to head coaches in the Atlantic Coast Conference (ACC). The award is granted to the head coach voted to be the most successful that season by members of the Atlantic Coast Sports Media Association, and since the 2012–13 season has also been awarded in separate voting by the league's coaches. The award was first given following the 1953–54 season, the first year of the conference's existence, to Everett Case of NC State. The first winner of the coaches' award was Jim Larrañaga of Miami (FL) in 2013.

Dean Smith of North Carolina has won the most awards with eight, followed by Mike Krzyzewski of Duke, with five, and currently active coach Tony Bennett of Virginia, with four. Fourteen coaches in total have won the award more than once. Fourteen coaches have also won the award in the same season that they have also won a National Coach of the Year award; of those, only Krzyzewski and Smith have achieved the feat three times. Five coaches have won during the same season that they have coached a team that won the NCAA Tournament Championship: Tony Bennett, Frank McGuire, Norm Sloan, Dean Smith, and Gary Williams. McGuire is the only head coach to win the award at two different schools (North Carolina and South Carolina).

Each of the original (1953) ACC members have had at least one of their coaches win the award. Among schools that joined the ACC before 2013, Boston College is the only one that has never had a winning coach. Thirty-one different coaches from twelve schools have received the award. North Carolina has the most ACC Coach of the Year awards with twelve, while its in-state rival, Duke, is second with ten. Each school of Tobacco Road (including NC State and Wake Forest) has won at least seven awards, as has Virginia with eight.
