The 1993 Atlantic Coast Conference baseball tournament was held in Greenville, SC from May 15 through 20. Clemson won the tournament and earned the Atlantic Coast Conference's automatic bid to the 1993 NCAA Division I baseball tournament.

All nine teams qualified for the conference tournament, with several byes allowing for a nine-team double-elimination tournament.

On Saturday (The Semifinals) of the ACC Baseball Tournament, the match-up between the four remaining teams is determined by previous opponents. If teams have played previously in the tournament, every attempt will be made to avoid a repeat match-up between teams, regardless of seed. If it is impossible to avoid a match-up that already occurred, then the determination is based on avoiding the most recent, current tournament match-up, regardless of seed. If no match-ups have occurred, the team left in the winners bracket will play the lowest seeded team from the losers bracket.

The brackets were set up without an elimination play-in game and several byes, which allowed all 9 teams to play in a double-elimination format. To clarify the brackets above, the match-ups (by round) to the reordered semifinals were as follows:

• 1st Round: Maryland vs. Georgia Tech, Clemson vs. Duke, Florida State - bye, N.C. State vs. Virginia, North Carolina vs. Wake Forest
• 2nd Round (winner's): Georgia Tech - bye, Clemson vs. Florida State, North Carolina vs. N.C. State
• 2nd Round (loser's): Duke vs. Maryland, Virginia vs. Wake Forest
• 3rd Round (winner's): Clemson vs. Georgia Tech, North Carolina - bye
• 3rd Round (loser's): Duke vs. N.C. State, Florida State vs. Virginia
• 4th Round (winner's): Clemson vs. North Carolina
• 4th Round (loser's): N.C. State - bye, Florida State vs. Georgia Tech

• College World Series
• NCAA Division I Baseball Championship
