The Philadelphia Phillies are a Major League Baseball team. They are the oldest continuous, one-name, one-city franchise in all of professional American sports, dating to 1883. The Phillies are a member of the Eastern Division of Major League Baseball's National League. Since 2004, the team's home has been Citizens Bank Park in the South Philadelphia section of the city.

The Phillies have won two World Series championships (against Kansas City in 1980 and Tampa Bay in 2008) and seven National League pennants, the first of which came in 1915. The franchise has also experienced long periods of struggle. The age of the team and its history of adversity has earned it the dubious distinction of having lost the most games of any team in the history of American professional sports. Notwithstanding the collectively poor performance over the years, the Phillies have performed much better in recent seasons, winning their division five times in a row since 2007.
