Eighth Corps Area was amilitary formation of theUnited States Army. Its headquarters was atFort Sam Houston, TX. It was established on 20 August 1920 with headquarters at Fort Sam Houston, TX, and organized from portions of the discontinued Southern Department.

For administrative purposes and for tactical control in connection with border patrol field operations, that part of the state of Arizona that lies west of the 114 degree meridian and south of the 33 degree parallel was attached to the Ninth Corps Area. In May 1927, the Pole Mountain Reservation and the post ofFort D. A. Russell (later renamed Fort Francis E. Warren) inWyoming came under the control of the Eighth Corps Area when the4th Infantry Brigade was transferred to that post from Fort Sam Houston. The installations were returned to control of the Ninth Corps Area on 1 July 1939.
