Pennsylvania Route 32 (PA 32) is a scenic two-lane highway that runs along the side of the Delaware River in Bucks County, Pennsylvania. It begins at U.S. 1 in Falls Township and ends at Pennsylvania Route 611 near the village of Kintnersville. Most notably it passes through Washington Crossing Historic Park, a Revolutionary War-themed historical park on the site of George Washington's crossing on the night of December 25–26, 1776. It also passes through the towns of Yardley and New Hope.

For most of its length the speeds are reduced to 35 mph (56 km/h), although there are sections of 45 mph. As such, it is more of a scenic river route than a highway and most motorists in Bucks County use parallel roads in that area. It is known as River Road throughout its length. The road is popular for Sunday drivers, bikers, fishermen, and viewers of fall foliage.

PA 32 begins at an incomplete interchange with U.S. Route 1 in Falls Township, 26 miles (42 km) northeast of Philadelphia. The highway enters the borough of Morrisville from the west as Bridge Street parallel to US 1. One mile east of the termini, PA 32 intersects Pennsylvania Avenue; motorists use this street to enter the US 1 expressway. PA 32 east of Pennsylvania Avenue turns north on to Delmorr Avenue and is parallel to the Delaware River. While parallel to the Delaware River, the highway intersects many bridges, two of which, US 1 and US 202, are one way toll into Pennsylvania from New Jersey. Outside of Morrisville, the highway continues its north alignment heading to the north and west.

While traversing Yardley, PA 32 is called Delaware Avenue and meets the eastern terminus of PA Route 332. North of the borough, the highway is known as River Road and passes under Interstate 95. North of the I-95 underpass, the road is parallel to the Delaware River and Pennsylvania Canal. In the town of Washington Crossing, the route traverses Washington Crossing Historic Park, the site where George Washington's troops crossed the Delaware River during the Revolutionary War. PA 32 meets PA Route 532 in downtown Washington Crossing. North of the park, the route travels on a north alignment with a couple of curves.

PA 32 enters New Hope from the south as Main Street, upon briefly intersecting the northern terminus of PA Route 232. The highway later intersects PA Route 179: another route that terminates at the New Jersey state line. North of New Hope, PA 32 interchanges with U.S. Route 202. In Centre Bridge, PA 32 meets the northern terminus of PA Route 263. The continues to curve along the Delaware River north of PA 263. The rest of the designation of PA 32 is parallel to the Delaware River. The highway terminates at junction with PA Route 611 in Nockamixon Township.

PA 32 was designated along its current alignment in 1928. The original alignment, created in 1925, followed the same route but continued south from Morrisville to Philadelphia. The PA 32 designation between Morrisville and Philadelphia was removed in favor of U.S. Route 13 in 1928. In 1932 a parkway was proposed along the route from Morrisville to New Hope, however, it was never built. In 1969, another proposal was created for a $30 million Pennsylvania Route 32 expressway from I-95 near Yardley to US 202 in New Hope. However, the proposal was canceled in 1974 due to low traffic volume and environmental issues.

Due to its route along the Delaware River, PA 32 is prone to floods. Several floods, including the Mid-Atlantic Flood of June 2006, left many parts of the road impassable. The sections of road between PA 263 and Greenhill Road and near Fleecydale Road in Solebury Township and between PA 611 and Narrows Hill Road in Nockamixon Township were closed from the damage. The Pennsylvania Department of Transportation undertook a $11.4 million project to fix these sections of road in 2008. The section between PA 263 and Greenhill Road was completed by Memorial Day 2008 and the section between PA 611 and Narrows Hill Road was completed in summer of 2008. Road closures and detours have affected many businesses along PA 32, with many seeing a decline in customers and some closing down or being put up for auction. However, the once-closed part of the far northern terminus in Nockamixon Township has been completed, and is now open for both northbound and southbound travelers.

The entire route is in Bucks County.
