1980 ACC Men's Basketball Tournament

The 1980 Atlantic Coast Conference Men's Basketball Tournament was held in Greensboro, North Carolina, at the Greensboro Coliseum from February 28 through March 1. Duke defeated Maryland 73–72 to win the championship. Maryland's Albert King was named the tournament MVP, becoming the last player to date (as of the 2015 tournament) to have been named MVP without playing on the tournament winners. Georgia Tech played in this event for the first time as the ACC returned to an eight-team configuration since the first time since the departure of South Carolina in 1971.
