U.S. Route 412 is an east–west United States highway, first commissioned in 1982. Its route number is a "violation" of the usual AASHTO numbering scheme, as it comes nowhere near its implied "parent", US 12. U.S. 412 overlaps expressway-grade Cimarron Turnpike from Tulsa west to Interstate 35 and the Cherokee Turnpike from 5 miles (8.0 km) east of Chouteau, Oklahoma, to 8 miles (13 km) west of the Arkansas state line. U.S. 412 has a special route in eastern Oklahoma named Scenic US 412, one of only two such routes in the country. Another curiosity of this highway is that it runs the entire length of the Oklahoma Panhandle and traverses the Missouri Bootheel.

As of 2004^[update], the highway's eastern terminus is in Columbia, Tennessee at an intersection with Interstate 65, where it continues east as State Route 99. Its western terminus is in Springer, New Mexico at an intersection with Interstate 25.
