Cesar Basa Air Base, or simply Basa Air Base (formerly known as Floridablanca Airfield) (ICAO: RPUF), is an airbase currently operated by the Philippine Air Force. It is located at Floridablanca, Pampanga about 40 miles (64 km) northwest of Metro Manila in the Philippines. It is named after César Basa, one of the pioneer fighter pilots of the Philippine Air Force.

The base was built and used by the US Army Air Corps before the Second World War and was captured and used by the Imperial Japanese Army Air Force during the early stages of World War II. Allied military forces recaptured it during the later stages of the war.
