King Shaka International Airport abbreviated KSIA, is the primary airport serving Durban, South Africa. Located in La Mercy, KwaZulu-Natal, approximately 35 km (22 mi) north of the city centre of Durban, it opened its doors to passengers on 1 May 2010, just over a month before the start of the 2010 FIFA World Cup. It replaced Durban International Airport (ICAO: FADN) and uses the same IATA airport code.

The airport forms part of the Dube TradePort, which will additionally consist of a trade zone linked to the airport's cargo terminal, facilities to support the airport such as nearby offices and transit accommodation for tourists, an integrated agricultural export zone, and an IT platform

The largest aircraft KSIA currently has scheduled services for is the Boeing 777-300ER, with Emirates operating Dubai–Durban, despite the fact that KSIA's runway length and terminal were designed to theoretically handle regular large airliners. In September 2015, during the World Routes Conference which was held in Durban (the first time on African soil), Turkish Airlines announced a new international service to Istanbul and Qatar Airways announced the commencement of service to Doha in December of that year.

On 27 January 2014 the world's largest passenger aircraft, an Airbus A380-800 of British Airways landed at KSIA becoming the first A380 to do so. The aircraft was being used for training and operated many flights in and out of the airport until 4 February 2014. The aircraft also returned for further pilot training between 29 August and 1 September the same year.
