Pennsylvania Route 73 (PA 73) is a 62.51 mi long east-west state highway in southeastern Pennsylvania. It runs from Pennsylvania Route 61 in Leesport to the New Jersey state line on the Tacony-Palmyra Bridge in Philadelphia, where it continues as New Jersey Route 73.

Predating the Interstate and U.S. Highway Systems, the Skippack Pike, a modern section of the route, served as the primary connector between Philadelphia and the northwest suburbs.
