U.S. Route 70 (abbreviated US-70) is a transcontinental U.S. highway extending from Globe, Arizona to Atlantic, North Carolina. Along the way, 289.81 miles (466.40 km) of its route passes through the state of Oklahoma. Entering the state south of Davidson, the highway serves Oklahoma's southern tier before exiting the state east of Broken Bow. It serves the cities of Ardmore, Durant, Hugo, and Idabel, as well as Tillman, Cotton, Jefferson, Carter, Marshall, Bryan, Choctaw, and McCurtain counties.

US-70 was first established in Oklahoma in 1926. The highway's initial path (which entered the state in Cotton County, further east than it does today) included several deviations from the present-day route, serving Walters and following a more northerly course between Ardmore and Madill. US-70 did not enter Tillman County until 1945. The modern route between Ardmore and Madill was not established until 1984 when it received the US-70 designation.
