Baseball at the 1988 Summer Olympics was a demonstration sport for the seventh time. Eight teams competed in Jamsil Baseball Stadium in the baseball tournament. The format used was the same as the tournament of four years earlier. Five teams that had competed in the 1984 tournament returned.
There were two pools for the preliminary round. Teams played each of the three other teams in their division.

The winners of the semifinals played each other for first and second place. In a rematch of the 1984 final, the reigning champion Japanese team lost to the United States. Since baseball was a demonstration sport, medals were awarded, but the medals were not "official" (and did not count in the respective nations' medal totals).
