The 2/48th Battalion was an infantry battalion of the Australian Army which served during the Second World War. Raised in Adelaide in South Australia in August 1940, the battalion formed part of the 26th Brigade and was initially assigned to the 7th Division, although it was later transferred to the 9th Division in 1941 when it was deployed to the Middle East. While there, it saw action during the siege of Tobruk and the First and Second Battles of El Alamein before being returned to Australia to take part in the fighting in New Guinea following Japan's entry into the war.
