Sultan Abdul Aziz Shah Airport (IATA: SZB, ICAO: WMSA) also known as Subang SkyPark, — formerly Subang International Airport/Kuala Lumpur International Airport, often called Subang Airport — is an airport located in Subang, Petaling District, Selangor, Malaysia. Serving as the main airport for Kuala Lumpur from 1965 to 1998, it was eventually replaced by the newer Kuala Lumpur International Airport (KLIA).

The airport serves as a central hub for regional and charter carriers, including Firefly and Berjaya Air. It continues to attract travelers from Kuala Lumpur due to its proximity to the city center and convenient location in the Klang Valley.

As of 2024, commercial jet operations have returned to Sultan Abdul Aziz Shah Airport, linking Subang to several regional destinations. It remains an important center for general aviation and domestic flights, with ongoing plans for further development. The airport is also aiming to become a leading center for Maintenance, Repair and Overhaul (MRO) services, as well as other aerospace activities in the region.
