State Highway 8, also abbreviated as SH-8 or OK-8, is a highway maintained by the U.S. state of Oklahoma. Because it runs mainly north–south, it has an even number (which is normal for Oklahoma state highways, but opposite from national highways). Highway 8 runs from U.S. Highway 277 in Cyril, Oklahoma to the state line south of Kiowa, Kansas, for a total length of 179.1 miles (288.2 km)^[1] The highway has two lettered spur routes.

Highway 8 dates from the creation of the state highway system in 1924. Initially a border-to-border route, it was shortened to its current extent due to encroaching U.S. highways. SH-8 has followed its current route since 1966.
