County Route 527 (CR 527) is a county highway in the U.S. state of New Jersey. The highway extends 84.8 mi (136.47 km) from Main Street (Route 166 and CR 549) in Toms River to Pompton Avenue (Route 23) in Cedar Grove. It passes through more counties (six) than any other county route in New Jersey. CR 527 is also the second longest 500-series county route in New Jersey after Route 519. The county route traverses through the northernmost stretches of the Pine Barrens in South Jersey, much of the Raritan Valley and Rahway Valley regions in Central Jersey (providing access to Monmouth Battlefield State Park, Rutgers-New Brunswick, Delaware and Raritan Canal State Park, Watchung Reservation, and South Mountain Reservation), and the First and Second Watchung Mountains in North Jersey.^[3][4][5][6] It passes through Ocean, Monmouth, Middlesex, Somerset, Union, and Essex counties on the eastern side of the state.

It has a 2.4 mile concurrency with Route 18 in Middlesex County in addition to other minor state highways and county roads. The route interchanges with the Garden State Parkway and Interstates 195, 95 (New Jersey Turnpike), 287, 78, and 280. It was first given the number 527 in 1954.
