The 2/12th Field Regiment was an Australian Army artillery regiment formed as part of the all volunteer Second Australian Imperial Force for overseas during World War II. Recruited in the state of Victoria in early 1940, the 2/12th was initially formed as a medium artillery regiment, but was later converted to a field regiment due to a lack of medium guns. As a field regiment, the 2/12th deployed to the Middle East where they supported the 9th Division in several battles during the North African Campaign in 1941–42, and undertook garrison duty in Lebanon. In early 1943, the regiment returned to Australia and subsequently fought in New Guinea, seeing action against the Japanese during the Huon Peninsula Campaign in 1943–44 and then the Borneo Campaign in 1945.
