1998 ACC men's basketball tournament

The 1998 Atlantic Coast Conference men's basketball tournament took place from March 5 to 8 in Greensboro, North Carolina, at the Greensboro Coliseum. North Carolina won the tournament for the second year in a row, defeating Duke in the championship game.

From 1998 to 2000, the ACC Tournament adopted a format that in  which the top-seeded team played the last-place team in the first round. The winner of this game received a bye into the semifinals. A second first-round game pitted the #7 seed versus the #8 seed. The winner of that game played the #2 seed in the quarterfinals.

Antawn Jamison of North Carolina was named tournament MVP.
