Route 34 is a state highway in the central part of the U.S. state of New Jersey. The route runs 26.7 mi (43.0 km) from an intersection with Route 35 and Route 70 (the former Brielle Circle) in Wall Township, Monmouth County, north to an intersection with US 9 in Old Bridge, Middlesex County. The route is a four-lane divided highway between its southern terminus and the north end of the Route 33 concurrency in Howell; along this stretch, the route intersects the Garden State Parkway and I-195/Route 138 within a short distance of each other. North of Route 33, Route 34 is an undivided two- to four-lane road that intersects Route 18 in Colts Neck and Route 79 in Matawan. Route 34 passes through mostly suburban areas along its route.

The route was legislated in 1927 to run from Route 35 (present Route 88) in Laurelton north to Route 4 (present Route 79) in Matawan. The current alignment of Route 34 north of Matawan was a part of Route 4 (and later US 9) until it became a part of Route 4A following a realignment of US 9 and Route 4. In 1953, Route 34 was extended north along Route 4A to end at US 9 in Old Bridge Township. Meanwhile, the southern terminus was cut back to its current location with the route south of that point becoming a part of Route 70. Since 1953, the southern portion of the route was widened into a divided highway and the Brielle Circle was replaced.
