The Fifth 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 III Corps that oversaw the region of the country surrounding the capital, Saigon.

The Fifth Division was based in Biên Hòa, a town on the northern outskirts of Saigon, and due to the Division's close proximity to Saigon was a key factor in the success or failure of the various coup attempts in the nation's history. As a result, the loyalty of the commanding officer of the Division was crucial in maintaining power.
