The 3rd Division of the Army of the Republic of Vietnam (ARVN)—the army of the nation state of South Vietnam that existed from 1955 to 1975—was part of the I Corps that oversaw the northernmost region of South Vietnam, the centre of Vietnam.
The Division was initially raised in October 1971 in Quảng Trị and composed of 2nd Infantry Regiment (from the 1st Division), 56th Infantry Regiment and 57th Infantry Regiment.
The division collapsed in 1972 during the Easter Offensive, was reconstituted and finally destroyed at Da Nang in 1975 during the Hue-Da Nang Campaign.
