The 1988 Montreal Expos season was the 20th season in franchise history. The Expos finished in third place in the National League East at 81–81, 20 games behind the New York Mets.

Offseason

Spring training

The Expos held spring training at West Palm Beach Municipal Stadium in West Palm Beach, Florida – a facility they shared with the Atlanta Braves. It was their 12th season at the stadium; they had conducted spring training there from 1969 to 1972 and since 1981.

Regular season

Opening Day starters

Expos pitcher Pascual Pérez threw a five-inning rain-shortened no-hitter against the Phillies on September 24, 1988. It was the first no-hitter in Veterans Stadium history. Perez allowed one walk, and another Phillies baserunner reached on an error. Umpire Harry Wendelstedt waved off the game after a 90-minute rain delay after the game was stopped by a steady rain with one out in the top of the sixth. However, due to a statistical rule change in 1991, no-hitters must last at least nine innings to count. As a result of the retroactive application of the new rule, this game and thirty-five others are no longer considered no-hitters.
