Philadelphia is the largest city in the U.S. state of Pennsylvania, with a metropolitan area population of 6.3 million as of 2024. Philadelphia is home to more than 350 completed high-rise buildings, 86 of which are 300 feet (91 m) or taller, as of 2026. Philadelphia has the largest skyline in Pennsylvania, and has the fourth most skyscrapers taller than 492 ft (150 m) in the Northeastern United States after New York City, Boston, and Jersey City. Seven of the ten tallest buildings in Pennsylvania are in Philadelphia; the remainder are in Pittsburgh. The tallest building in Philadelphia is the Comcast Technology Center, the city's sole supertall skyscraper, and the tallest building in the United States outside of New York City and Chicago. The 1,113 ft (339 m), 59-story building was opened in 2018.
Philadelphia has an extensive history of tall structures, generally thought to have begun with the 1754 addition of the steeple to Christ Church. The Philadelphia City Hall was the first building in the world to surpass a height of 500 ft (152 m) when it topped out in 1894, and remained the world's tallest building until 1908. Philadelphia had one of the largest pre-war construction booms in the United States, having built 18 buildings taller than 300 ft (91 m) by the early 1930s, the most of any city in the world besides New York City and Chicago. The Great Depression and World War II halted skyscraper development until the late 1950s. From the 1960s to 1980s, Philadelphia added a large number of office buildings to its skyline in a second boom. For most of the 20th century, a "gentlemen's agreement" imposed an unofficial height limit, restricting the height of any new skyscraper below that of the 548-foot (167 m) Philadelphia City Hall.
This agreement was broken with the topping out of One Liberty Place in 1987; at 945 feet (288 m), it exceeded the height of the city hall by almost 400 feet (122 m). Its twin, Two Liberty Place, was completed in 1990, near the end of the boom. Little development occurred during the 1990s, while a fire at One Meridian Plaza led to the rare demolition of a notable skyscraper in 1998. Construction resumed in the 2000s, with an increasing share of residential development. Comcast, which is based in Philadelphia, is responsible for the city's two tallest buildings. The 973 ft (297 m) Comcast Center was completed as the company's headquarters in 2008. It was the city's tallest building until the adjacent Comcast Technology Center was built in 2018, whose central floors house additional office space for Comcast.
Despite being one of the oldest cities in the United States, the twelve tallest buildings in Philadelphia were all built after 1986, due to the former gentlemen's agreement. Philadelphia's tallest buildings are largely concentrated in Center City, the city's central business district, mainly on its western half. Delaware River marks the end of the skyline to the east. Since the 2000s, Philadelphia's skyline has also expanded westwards past the Schuylkill River, towards University City. At 730 ft (223 m), FMC Tower at Cira Centre South is the Philadelphia's tallest building outside of Center City. The Schuykill Yards development plans to add several new skyscrapers to a plot of land northeast of Drexel University. A few high-rises can be found in and around Temple University, north of Center City.

The map below shows the location of buildings taller than 300 feet (91.4 m) in Philadelphia. Each marker is numbered by height and colored by the decade of the building's completion. Two buildings, The Regatta and Temple University - Morgan Hall North, are not visible.
This list ranks completed and topped out skyscrapers in Philadelphia that stand at least tall as of 2026, based on standard height measurement. This includes spires and architectural details but excludes antenna masts. The "Year" column indicates the year in which a building was completed. Buildings tied in height are sorted by year of completion with earlier buildings ranked first, and then alphabetically.
In addition to those in the city of Philadelphia, there are two buildings located in the Philadelphia metropolitan area that are taller than 300 feet (91 m).
The following table ranks buildings under construction in Philadelphia that are expected to be at least 300 ft (91 m) tall as of 2026, based on standard height measurement. The âÂÂYearâ column indicates the expected year of completion. Buildings that are on hold are not included.
The following table ranks approved buildings in Philadelphia that are expected to be at least 300 ft (91 m) tall, based on standard height measurement. The âÂÂYearâ column indicates the expected year of completion. A dash âÂÂâÂÂâ indicates information about the building is unknown or not released.
The following table ranks proposed buildings in Philadelphia that are expected to be at least 300 ft (91 m) tall, based on standard height measurement. A dash âÂÂâÂÂâ indicates information about the building is unknown or not released.
There have been three buildings taller than 300 ft (91 m) in Philadelphia that no longer stand today.
Philadelphia has seen few city record-holders compared to other cities with comparable skylines. Although churches, cathedrals, and the like are not technically considered to be skyscrapers, Christ Church, after being surmounted with its lofty spire in 1754, stood as its tallest building for 102 years before being surpassed by the (no longer extant) spire of Tenth Presbyterian Church, which was surpassed by City Hall in 1894. Then, due to the "gentlemen's agreement" not to build higher than the top of the statue of William Penn atop City Hall, that building stood as the city's tallest structure for 93 years; it also held the world record for tallest habitable building from 1894 until the 1908 completion of the Singer Building in New York City.
