RAAF Base Williamtown (IATA: NTL, ICAO: YWLM) is a Royal Australian Air Force (RAAF) military air base located 8 nautical miles (15 km; 9.2 mi) north of Newcastle (27 km (17 mi) by road) in the local government area of Port Stephens, in New South Wales, Australia.^[1] The base serves as the headquarters to both the Air Combat Group and the Surveillance and Response Group of the RAAF. The nearest towns are Raymond Terrace, located 8 km (5 mi) west of the base and Medowie, 6.8 km (4.2 mi), north of the base, which is home to many of the base's staff.

The base operates a single runway which is shared with the Newcastle Airport under a lease agreement where the Department of Defence leases rights to use the runway to Williamtown Airport.^[2] A number of the buildings and other facilities on the base are listed on the Commonwealth Heritage List.^[3]
