The 2/9th Field Regiment was an Australian Army artillery regiment formed as part of the all volunteer Second Australian Imperial Force in July 1940 for operations during World War II. Assigned to the 1st Australian Corps, the regiment was sent to the Middle East in mid-1941, and served in Palestine, Egypt, and Syria before returning to Australia in 1942. It undertook defensive duties in south-east Queensland before deploying north to Merauke, in Dutch New Guinea, and Cape York. It returned to Australia in October 1944 and sent to the Atherton Tablelands to carry out training as it waited for further deployment. This never came and the regiment was disbanded in late 1945.
