List of tallest buildings in Pennsylvania

This list of the tallest buildings in Pennsylvania includes all skyscrapers 400 feet (120 m) or taller, ranked by height. The tallest building in Pennsylvania is the 60-story Comcast Technology Center in Center City Philadelphia, which is 1,121 feet (342 m) in height. The building opened in 2018.[1][2] It is currently the 14th-tallest building in the United States.

Among Pennsylvania cities, Philadelphia has the most buildings exceeding 400 feet (120 m) in height with 34 followed by Pittsburgh with 16. Excluding buildings in these two cities, the tallest buildings elsewhere in the state are Scranton Times Tower in Scranton, PA at 385 ft (117 m)- although this is a radio tower atop a 5-story structure, 333 Market Street in Harrisburg at 341 ft (104 m), Martin Tower (recently demolished) in Bethlehem at 332 ft (101 m), PPL Building in Allentown at 322 feet (98 m), and the Berks County Courthouse in Reading, PA at 275 ft (84 m). The Comcast Technology Center is not the tallest freestanding structure in Pennsylvania as that would go to the Unit 3 original smokestack in Homer City at 1,217 feet tall.
