State Highway 56 (abbreviated SH-56 or OK-56) is a state highway in the U.S. state of Oklahoma. The road serves Seminole County, Okfuskee County, and Okmulgee Counties in central and east-central Oklahoma. In Seminole County, it is also designated as the Seminole Nation Highway in honor of the contributions the Seminole Nation has made to the state of Oklahoma.^[2]

SH-56 begins at an intersection with US-377 four miles (6 km) east of Konawa,^[3] and extends to US-75 in Okmulgee. The highway's total length is 86.7 miles (139.5 km).^[1]

SH-56 was first added to the state highway system in 1929. It was gradually extended to its present length between then and 1942.^[2]
