The Philadelphia Baseball Wall of Fame is a collection of plaques, mounted on a brick wall next to the Left Field Gate at Citizens Bank Park, the ballpark of the Philadelphia Phillies. From 1978 to 2003, the Phillies inducted one figure from their franchise history and one notable person from the Philadelphia Athletics (A's) organization each year—with the exception of 1983, when the Phillies inducted their Centennial Team. Once Veterans Stadium closed in 2003, the wall plaques used to recognize the Phillies' members were moved to Citizens Bank Park; however, the Phillies no longer induct notable Athletics. Each person inducted into the Wall of Fame was honored with a metal plaque showing the person's face; their position with, and years of service to the team; and a summary of their most important contributions. In March 2004, the Athletics' plaques were relocated to the Philadelphia Athletics Historical Society in Hatboro, Pennsylvania, and a single plaque listing all of the A's inductees was attached to a statue of Connie Mack located across the street from Citizens Bank Park. After the Philadelphia Athletics Historical Society closed its Hatboro location in 2013, the Athletics’ plaques were put on display at Spike’s Trophies in Philadelphia, among other memorabilia of the team..

The history of the Philadelphia Phillies of Major League Baseball's National League began on November 1, 1882, with the organization of the Philadelphia Ball Club Limited. In 1883, this organization won the franchise rights to Philadelphia when the city was selected to replace the Massachusetts-based Worcesters, who had folded after the 1882 season.
