List of unsigned Oklahoma State Highways

This is a list of unsigned State Highways in the U.S. state of Oklahoma. Many of these are unsigned due to their short length. Others are state highways but have not been designated a state highway number.

All highways listed here are Oklahoma numbered highways. Oklahoma has one unsigned Interstate highway; see Interstate 444 for details. State highways that are numbered as lettered spur routes (e.g. SH-81A) are not listed here; see the article on the parent route for details on the spur.
