The Philadelphia Phillies are an American professional baseball team based in Philadelphia. They compete in Major League Baseball (MLB) as a member of the National League (NL) East division. Since 2004, the team's home stadium has been Citizens Bank Park, located in South Philadelphia. The Phillies are the oldest, continuous, one-name, one-city franchise in American professional sports. The Phillies have won two World Series championships (against the Kansas City Royals in and the Tampa Bay Rays in ) and seven National League pennants, the first of which came in 1915. Since the first modern World Series was played in the Phillies played 77 consecutive seasons (and 97 seasons from the club's establishment) before they won their first World Series—longer than any of the other 16 teams that made up the major leagues for the first half of the 20th century. They are one of the more successful franchises since the start of the Divisional Era in Major League Baseball. The Phillies have won 11 division titles, including five consecutive division titles from 2007 to 2011; these are ranked sixth among all teams and fourth in the National League. The franchise was founded in Philadelphia in 1883, replacing the team from Worcester, Massachusetts, in the National League. The team has played at several stadiums in the city, beginning with Recreation Park and continuing at Baker Bowl; Shibe Park, which was later renamed Connie Mack Stadium in honor of the longtime Philadelphia Athletics manager; Veterans Stadium, and now Citizens Bank Park.

Another Class-A, affiliate, the Lakewood BlueClaws play in Lakewood, New Jersey. The Phillies' Double-A affiliate is the Reading Fightin Phils, which play in Reading, Pennsylvania.
