The Battle of Binh Ba was a battle between soldiers of the Australian Army, North Vietnamese Army, and Vietcong during the Vietnam War.

Binh Ba village situated some four miles North of the Australian Task Force HQs at Nui Dat (10°33′22.2″N 107°13′22.5″E / 10.556167, 107.222917 (Nui Dat)) and on the western side just off Route 2 with a population of around one thousand, made up of mainly farmers and rubber plantation workers. The village houses were constructed of solid brick and tile. The village was well known to the Australians during the first tour and 5RAR stationed a rifle company and a mortar section within the village. This strategy proved to be a deterrent to the Viet Cong tax collectors and assassination squads taking control of the village. This however, was not to continue. In 1969 as the drain on the meagre resources of the Battalion proved to be too much and the village was left to the protection of Regional forces.
