Route 24 is a 10.4-mile (16.74 km) freeway in New Jersey, United States, that begins at a junction with I-287 in Hanover in Morris County, passes southeast through Essex County, and ends at a interchange with I-78 in Springfield in Union County.

The route was created in 1927 to run from Phillipsburg to Newark, replacing pre-1927 Route 12 from Phillipsburg to Penwell and Pre-1927 Route 5 from Morristown to Newark. The route was extended west to the new Easton–Phillipsburg Toll Bridge in 1938 but was cut back to U.S. Route 22 (US 22) in the eastern part of Phillipsburg in 1953. The western terminus was cut back further around 1970 to Hackettstown with the route west of there becoming part of Route 57. The freeway alignment of Route 24 between JFK Parkway and I-78 was completed in 1976.

With the completion of this freeway, Route 24 east of JFK Parkway became Route 124. The freeway was completed between the abandoned Triborough Road interchange and the JFK Parkway interchange in the 1970s but was not opened until 1992, when the rest of the freeway to I-287 was completed after years of legal, environmental and budgetary problems. At this time, the alignment of Route 24 between US 202 in Morristown and JFK Parkway became a western extension of Route 124 while the route was officially eliminated between Hackettstown and Morristown as it followed county-maintained routes. The former route between Hackettstown and Morristown is still referred to as Route 24 by many and is still signed as such due to local outcry.
