Leeuwarden Air Base (Dutch: Vliegbasis Leeuwarden) is a military airbase used by the Royal Netherlands Air Force (RNLAF) - Dutch: Koninklijke Luchtmacht (KLu), (IATA: LWR, ICAO: EHLW). The airbase was formerly one of the two F-16 Fighting Falcon bases of the RNLAF. The airbase lies northwest of the capital of Friesland, Leeuwarden.

Leeuwarden Air Base is also one of the three military airbases (together with Gilze-Rijen Air Base and Volkel Air Base) that organise the twice-in-three-years Luchtmachtdagen ('Air Force Days') of the Royal Netherlands Air Force, consisting of air shows and static exhibits. In 2006, 2008, 2011 and 2016 Leeuwarden Air Base hosted these public demonstration days.
