The 11th Parachute Battalion was an airborne infantry battalion of the Parachute Regiment, raised by the British Army during the Second World War. The battalion formed in the Middle East was assigned to the 4th Parachute Brigade, 1st Airborne Division. As it was still training it was left behind when the rest of the brigade took part in the Allied invasion of Italy. One company later parachuted onto the island of Kos taking prisoner the large Italian garrison. The battalion rejoined the rest of the division in England. The only battle in which the battalion participated was the Battle of Arnhem in September 1944. The battalion sustained heavy casualties and was disbanded following the battle.
