The 63rd Readiness Division is a base and administrative support formation of the United States Army Reserve (USAR). It is responsible for USAR units throughout the seven-state region of southwestern United States including California, Nevada, Arizona, New Mexico, Oklahoma, Texas and Arkansas.

The 63rd RSC traces its history to the 63rd Infantry Division ("Blood and Fire"), an infantry division of the Seventh Army of the Sixth United States Army Group of the Army of the United States that fought in Europe during World War II. After the war it was inactivated, but later the division number and shoulder sleeve insignia were authorized for use by the 63rd Army Reserve Command (ARCOM) of the United States Army Reserve.

Although the 63rd Regional Readiness Command located in Los Alamitos, CA, was not authorized to carry the lineage of the 63rd Infantry Division, the creation of the new 63rd Readiness Division in Moffett Field, CA, authorizes it to inherit the lineage and the bi-color red and blue background 63rd Infantry Division flag as an exception to policy. The unit was inactivated on 6 December 2009 and replaced by the 79th Sustainment Support Command, and was reactivated as a regional support command.
