State Highway 32 (SH-32 or OK-32) is a state highway in the U.S. state of Oklahoma. The highway runs from west to east across the southern part of the state, just north of the Red River. The route begins at US-81 in Ryan and ends at US-70 in Kingston, a length of 77.3 miles (124.4 km).SH-32 was first added to the state highway system at the end of 1934; none of the highway as created is part of the present-day SH-32 (having been encroached upon by US-70).
