State Highway 58 (abbreviated SH-58) is the name of two state highways in Oklahoma. One of them runs for 72.7 miles (117.0 km) from Medicine Park to the Blaine–Custer County line near Hydro,^[1] and the other connects US-270/281/SH-3/33 to the Kansas state line, a length of 105.9 mi (170.4 km).^[3] The northern section has one lettered spur route, SH-58A.

SH-58 was originally a part of US-164. When US-164 was decommissioned in 1930, a section of the road in Major County that was left without a designation became SH-58. Since then, the highway has grown toward both the north and the south. With the designation and extension of the southern section of the highway, SH-58 is present in five counties in the western part of the state.
