Route 73 is a state highway in the southern part of the U.S. state of New Jersey. It runs 34.64 mi as an outer bypass of the Camden area from an intersection with U.S. Route 322 in Folsom, Atlantic County to the Tacony-Palmyra Bridge in Palmyra, Burlington County, where it continues into Philadelphia, Pennsylvania as Pennsylvania Route 73. South of the interchange with the Atlantic City Expressway in Winslow Township, Camden County, Route 73 is a two-lane undivided county-maintained road and is signed as County Route 561 Spur, a spur of County Route 561 (CR 561). North of the Atlantic City Expressway, the route is maintained by the New Jersey Department of Transportation and is mostly four lanes, with the portion north of the County Route 561 concurrency a divided highway. North of the U.S. Route 30 (US 30) interchange near Berlin, Route 73 runs through suburban areas of the Delaware Valley, intersecting Route 70 in Marlton, the New Jersey Turnpike and Interstate 295 (I-295) in Mount Laurel Township, Route 38 and Route 41 in Maple Shade Township, Route 90 in Cinnaminson Township, and U.S. Route 130 in Pennsauken Township.

What is today Route 73 between the Tacony-Palmyra Bridge and Berlin was legislated as Route S41 in 1927, a spur of Route 41. An extension of this spur called Route S41A was designated in 1938 to continue south from Berlin to Route 42 (now U.S. Route 322) in Folsom. In 1953, both these routes became Route 73 in order to match Pennsylvania Route 73. The portion of Route 73 between Berlin and the Atlantic City Expressway became a state highway by 1969. By the 2000s, Route 73 was extended south along County Route 561 Spur to U.S. Route 322. Several traffic circles along Route 73 have been modified or replaced over time. Among these was the Berlin Circle, which was turned into an at-grade intersection in 2006. The Marlton Circle at Route 70, which was modified in 1974 to allow Route 73 to pass through the circle, is planned to be replaced with an interchange to be complete in 2011.
