The Nationals–Phillies rivalry is a Major League Baseball rivalry between the Washington Nationals and the Philadelphia Phillies of the National League East division. The series was previously known as the Expos–Phillies rivalry when Nationals franchise was previously known as the Montreal Expos. The franchise relocated to Washington, D.C., in 2005. The two teams clashed frequently for control of the division during much of the 1980s and 1990s. The first postseason matchup between the two teams occurred during the 1981 National League Division Series, resulting in the Expos winning the series 3–2. The rivalry regrew in intensity following the Expos' relocation and rebranding given the proximity of Washington, D.C., and Philadelphia.
