The 1979 Montreal Expos season was the 11th in franchise history. The team finished second in the National League East with a record of 95–65, 2 games behind the first-place Pittsburgh Pirates. The 1979 season was the Expos first winning season in franchise history (and it would be the most wins they would have in a season in the team's history before they relocated).
