Pennsylvania Route 252 (PA 252) is a north–south state highway in the U.S. state of Pennsylvania that connects PA 320 in Nether Providence Township at its southern terminus to PA 23 in Valley Forge at its northern terminus. The route runs through the western suburbs of Philadelphia in Delaware, Chester, and Montgomery counties, including Nether Providence Township, the borough of Media, Upper Providence Township, Marple Township, Newtown Township, Easttown Township, Tredyffrin Township, and Upper Merion Township. The route intersects many roads including U.S. Route 1 (US 1) north of Media, PA 3 in Newtown Square, US 30 in Paoli, and US 202 near Berwyn.

The southernmost part of PA 252 was originally built as part of the Providence Road in 1684. PA 252 was designated by 1928 to run from PA 320 north of Chester north to US 122/PA 52 (now US 202) in King of Prussia. By 1960, the northern terminus was moved to PA 23 in King of Prussia. PA 252 was realigned to head to its current northern terminus at Valley Forge by 1970, running along a concurrency with US 202 (removed by 1980) for a distance north of Paoli and replacing a part of PA 363 (formerly PA 83) in the Valley Forge area.
