The 1984 Montreal Expos season was the 16th season in franchise history. They recorded 78 wins during the 1984 season and finished in fifth place in the National League East. A managerial change occurred as Bill Virdon was replaced by Jim Fanning. The highlight of the Expos season was the acquisition of Pete Rose. After being benched in the 1983 World Series, Rose left the Phillies and signed a one-year contract with the Montreal Expos. He garnered his 4,000th hit with the team on April 13, 1984 against the Phillies, being only the second player to do so.
