Pennsylvania Route 179 (PA 179) and Route 179 is an 8.77 mi state highway in Bucks County, Pennsylvania and Hunterdon County, New Jersey, United States, running along an old alignment of U.S. Route 202 (US 202) from west of New Hope, Pennsylvania northeast through Lambertville, New Jersey to Ringoes, where it ends at an intersection with US 202 and Route 31. Past this intersection, the road continues east as County Route 514 (CR 514). It is two-lane, undivided highway for most of its length with the exception of a four-lane stretch in Lambertville. The route crosses the Delaware River on the New Hope-Lambertville Bridge, where the designation changes from PA 179 to Route 179.

PA 179 and Route 179 follow a part of the 18th-century Old York Road which ran between Philadelphia and New York City. Prior to 1953, the road was Route S29 from the Delaware River to downtown Lambertville, a part of Route 29 between Lambertville and Ringoes, and a concurrency of Route 29 and Route 30 in Ringoes. The route was also part of US 202, which was designated over 1926-created US 122 in the mid-1930s. In 1953, the Route S29 and 29 designations were removed in favor of US 202 and Route 30 became Route 69 (now Route 31). Route 179 was formed in 1965 when a bypass for Ringoes was built for US 202 and Route 69. Route 179 extended to Lambertville and PA 179 was created in 1974 when the new US 202 freeway, running over the New Hope-Lambertville Toll Bridge, was completed.
