There have been a number of 19th Divisions in the history of the United States Army.

World War II

The third iteration was the 19th Armored Division was constituted in the Army of the United States on 18 January 1943, however, it was never officially activated during the war.

The headquarters was activated on 15 January 1947 at Los Angeles, California, and the Headquarters Company was activated on 1 July 1947. Both units were inactivated on 20 August 1947 and reflagged as the 13th Armored Division and activated the next day.[5] The 19th Armored Division was disbanded on 21 March 1952.
