Fort Cobb was a United State Army post established in what is now Caddo County, Oklahoma in 1859 to protect relocated Native Americans from raids by the Comanche, Kiowa and Cheyenne.
The fort was abandoned by Maj. William H. Emory at the beginning of the Civil War and remained abandoned until it was reoccupied in 1868. After establishing Fort Sill the Army abandoned Fort Cobb. Today there is little left of the former military post.
