The 306th Armored Cavalry Regiment (306th ACR) was a District of Columbia-based reconnaissance unit of the United States Army Organized Reserve Corps that briefly existed after World War II. The 306th ACR later became a group before being inactivated in 1959.

It traced its history back to the 306th Cavalry Regiment, a reserve unit that existed during World War I and the interwar period. It was activated in early 1918 but broken up in the middle of the year to form new artillery units. The unit was recreated as a Maryland Organized Reserve unit during the interwar period, and was converted into a signal aircraft warning regiment after the United States entered World War II.
