The 1981 Montreal Expos season was the 13th season in franchise history. They made it to the postseason for the first time in franchise history (the franchise's next appearance in the playoffs was in 2012, as the Washington Nationals). Their playoff run ended in the National League Championship Series against the Los Angeles Dodgers, with Rick Monday hitting a ninth-inning solo home run in game 5, subsequently referred to as "Blue Monday" by Expos fans. This was the closest the Expos ever got to a World Series appearance while in Montreal.
