New Jersey State Highway 37 is a state highway in New Jersey, United States. It runs from Lakehurst, New Jersey at an intersection with New Jersey State Highway 70 to an intersection with New Jersey State Highway 35 in Seaside Heights, New Jersey.

At one point, NJ 37 was supposed to run from Trenton, New Jersey at the White Horse Circle to Point Pleasant, New Jersey. Several disjointed sections of NJ 37 were built prior to 1990 in preparation for a proposed extension. This was never built and Interstate 195 (see Interstate 95) partially filled the gap.
