The Paya Lebar Air Base (IATA: QPG, ICAO: WSAP) is a military airbase of the Republic of Singapore Air Force (RSAF) in Singapore located at Airport Road in Paya Lebar, in the eastern region of Singapore. The airbase goes by the motto of Strength Through Readiness.

It was originally built in 1954 as Singapore International Airport to replace Kallang Airport; control of the airport was transferred to RSAF in 1980 when it was renamed Paya Lebar Air Base, following the relocation of the civilian airport to Changi.

Under the Urban Redevelopment Authority (URA)'s Master Plan, Paya Lebar Air Base is scheduled to be decommissioned by around 2030 to make way for residential and commercial developments as a new town, with the RSAF relocating to other airbases throughout the country such as at Changi and Tengah, which will be expanded throughout the 2020s.
