State Highway 14, abbreviated as SH-14, is a highway maintained by the U.S. state of Oklahoma. It is 27.85 miles (44.82 km) long, with its entire route falling in Woods County in the northwestern part of the state. It does not have any lettered spur routes. SH-14 was part of Oklahoma's original highway system, as designated on August 24, 1924, and ran from Frederick in southwestern Oklahoma to the Kansas state line. In the late 1930s, however, new U.S. routes were introduced to Oklahoma; U.S. Highway 281 (US-281) and US-183 overtook most of SH-14's route, reducing it to its present-day extent.
