The 2024 ACC men's basketball tournament was the postseason men's basketball tournament for the Atlantic Coast Conference held at the Capital One Arena in Washington, D.C., from March 12 to 16, 2024. It was the 71st annual edition of the tournament. The NC State Wolfpack won the title as the tenth seed, winning five games in five days to become tournament champions. They were the lowest seed to win the tournament and the first team to win five games in five days since UConn accomplished the feat to win the 2011 Big East Tournament. As champions, NC State earned the ACC's automatic bid to the 2024 NCAA tournament.
All 15 ACC teams participated in the tournament. Teams were seeded by record within the conference, with a tiebreaker system to seed teams with identical conference records.
