Baseball at the 1988 Summer Olympics was a demonstration sport for the seventh time.

Cuba originally qualified but withdrew as a result of the boycott.

Thus, Japan (3-0) played against Korea (2-1), which had a tied record with the United States (2-1) but had lost in head-to-head competition against them.

In a rematch of the 1984 final, the reigning champion Japanese team lost to the United States.

Since baseball was a demonstration sport, no official medals were awarded.
