The 1955 Philadelphia Phillies season was the 73rd season in the history of the franchise, and the 18th season for the Philadelphia Phillies at Connie Mack Stadium. It was the first season for Phillies' manager Mayo Smith. Prior to the season, the Phillies were seen to have strong pitching with ace Robin Roberts but did not have power hitters to match pennant favorites Brooklyn, New York, or Milwaukee, behind whom the Phillies finished in fourth place with a record of 77–77.

Offseason Prior to the 1955 season, the Phillies purchased the Ballantine Beer electronic scoreboard from Yankee Stadium for $175,000 from the Yankees. It was placed in right-center field at Connie Mack Stadium. This scoreboard was used through the final year at the ballpark.

Baseball Commissioner Ford Frick, National League president Warren Giles, American League president Will Harridge, Clearwater mayor Herbert M. Brown, and other city dignitaries were in attendance. The Phillies played their first game at the stadium on the day of the dedication. Robin Roberts started for the Phillies against the Detroit Tigers. The Phillies won 4–2 on a two-run double by Willie Jones before 4,209 attendees.
