Route 77 is a state highway in the southern part of the U.S. state of New Jersey. It runs from an intersection with Route 49 in Bridgeton in Cumberland County north to a junction with Route 45 in Mullica Hill in Gloucester County. It is a mostly two-lane, undivided road traversing through farmland in Cumberland, Salem, and Gloucester Counties. Along the way, Route 77 intersects Route 56 in Upper Deerfield Township and U.S. Route 40 (US 40) in Upper Pittsgrove Township.
Prior to 1927, the route was a branch of pre-1927 Route 6 that ran from Bridgeton to Mullica Hill. In 1927, it was designated as Route 46, which replaced the Bridgeton-Mullica Hill branch of pre-1927 Route 6. In 1953, it was renumbered to Route 77 to avoid conflicting with US 46 in the northern part of the state.

Route 77 heads north from Route 49 and County Route 609 (CR 609) in Bridgeton, Cumberland County on Pearl Street. In a short distance, the route intersects CR 670 and then crosses CR 552, which ends a block to the west at Laurel Street. It continues north through residential areas of Bridgeton, meeting CR 665 and CR 659. Route 77 heads into a commercial area, passing under a Winchester and Western Railroad line and crossing into Upper Deerfield Township at the junction with Laurel Plaza Drive. The route intersects the western terminus of Route 56 and CR 622, where the route is briefly a four-lane road. Past this junction, Route 77 heads into farmland, where it encounters several county roads including CR 704, CR 617, and CR 658. Prior to 1927, the route was a branch of pre-1927 Route 6, which had run south from Camden and split into two branches in Mullica Hill that ran to Salem and Bridgeton. In the 1927 New Jersey state highway renumbering, Route 46 was designated along the former branch of pre-1927 Route 6 that ran from Bridgeton to Mullica Hill. In the 1953 New Jersey state highway renumbering, which stated that no state route and U.S. route could share the same number, Route 46 was changed to Route 77 to avoid a conflict with US 46 in North Jersey.
