State Road 456 is a 58.784-mile (94.604 km) long (94.604 km long) state highway in northeast New Mexico. It runs from Folsom, New Mexico at State Road 325 to the Oklahoma state border west of Kenton, Oklahoma. After crossing the Oklahoma border it becomes State Highway 325.

SR 456 parallels the Cimarron River for its entire length. It does not leave Union County. It is a former routing of U.S. Route 64. Seventeen consecutive miles of it are unpaved, as per signs at each end of the unpaved stretch; their main purpose is to warn of potential impassability in inclement weather. The stretch does have two spots of pavement, nevertheless: one about eight miles (13 km) in from the west, which is only about 100 feet (30 m) long, and one about fourteen miles (21 km) in from the west, which often fakes drivers out since it is so near to the end of the advertised length (its pavement lasts about a half mile). The drive has some nice scenic views, including one reminiscent of Colorado's Garden of the Gods; but its remoteness is not amicable to tourists having automobile breakdowns.
