MacDonald Airfield was an airfield built alongside the former northern road, west of Stuart Highway, north of Pine Creek, Northern Territory, Australia during World War II. The airfield was constructed by the 43rd Engineer Regiment (US Army) in March 1942 with further improvements undertaken by the 808th Engineer Aviation Battalion between 11 May 1942 and 16 July 1942 and later by the Allied Works Council and No 1 Airfield Construction Unit RAAF. The Royal Australian Air Force occupied the base on 24 November 1942 when No. 54 Operational Base Unit administered the base.
