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)^a in 2013.

Dean Smith of North Carolina has won the most awards with eight. Thirteen other coaches have won the award more than once. Five former ACC Coaches of the Year have been inducted into the Naismith Memorial Basketball Hall of Fame as coaches; Mike Krzyzewski (inducted 2001) of Duke and Roy Williams (inducted 2007) of North Carolina are the only two active coaches who are already members.

Fourteen coaches have 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. Four coaches have won during the same season that they have coached a team that won the NCAA Men's Division I Basketball Championship: Frank McGuire, Norm Sloan, Dean Smith, and Gary Williams. North Carolina has the most ACC Coach of the Year awards with 12, while its in-state rival, Duke, is second with 10. Frank 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.
