The 13th (Lancashire) Parachute Battalion was an airborne infantry battalion of the Parachute Regiment, raised by the British Army during the Second World War. The battalion was formed in May 1943 by the conversion of the 2/4th Battalion, South Lancashire Regiment to parachute duties and was assigned to the 5th Parachute Brigade in the 6th Airborne Division. A new 13th Parachute Battalion (TA) was raised when the Territorial Army was reformed in 1947. Over the years, as a result of a number of amalgamations, this battalion eventually became part of the present day 4th Battalion.
