Baseball at the 1984 Summer Olympics was a demonstration sport. Although single exhibition games had been played in conjunction with five previous Olympics, it was the first time that the sport was officially included in the program, and also the first time that the sport was played in Olympics held in the United States. Eight teams competed in Los Angeles, California in the tournament. Games were held at Dodger Stadium. Cuba, after winning the gold medal at the 1983 Pan American Games, was to participate, but did not as a result of the Soviet-led boycott.
There were two pools for the preliminary round. Teams played each of the three other teams in their division.
