The 2/9th Commando Squadron was a commando unit raised by the Australian Army for service in World War II. Raised in 1944, the unit saw action late in the war against the Japanese during the Aitape-Wewak campaign taking part in number of long range patrol operations across the Torricelli Range in New Guinea before being used in an amphibious landing near Wewak in May 1945. After the war the unit was disbanded.
