Mareeba Airfield (IATA: MRG, ICAO: YMBA) is an airfield located 4.3 nautical miles (8.0 km; 4.9 mi) south of Mareeba, Queensland, Australia. Built in 1942 as a US Army Air Force base during World War II, the airfield had two runways, with a complement of taxiways, hardstands and a containment area. After the war, much of the airfield reverted to agricultural use, while the southern runway remains as an active airfield.

A major US Army Air Force Base during World War II, Mareeba housed both heavy bomber and fighter squadrons of that Service in 1942 and 1943. The Americans referred to it as Hoevet Field in honor of Major Dean Carol "Pinky" Hoevet who was killed on 16 August 1942. Known USAAF units assigned were:

• 19th Bombardment Group, (Headquarters) (24 July 1942 – 23 October 1943)

The airfield became operational in May 1942 with the first lodger unit being 100 Squadron RAAF. Following their departure in early July, the airfield was occupied by USAAF heavy bomber squadrons from the US 5th Air Force which flew hundreds of bombing raids on enemy targets in the South Pacific; most notably Rabaul. With the departure of the American units, Mareeba was used by No 5 Communication Unit and a variety of Royal Australian Air Force (RAAF) support units, with No 24 Operational Base Unit disbanding in early 1946.

Today, the airfield hosts a museum with several World War II vintage airplanes on display in a flyable condition, and a major maintenance facility for Mission Aviation Fellowship.The airfield is home for the North Queensland Aero Club.
