Khartoum International Airport (IATA: KRT, ICAO: HSSK) (Arabic: مطار الخرطوم الدولي) is the principal airport in Khartoum, the capital of Sudan. The airport has been shut down since it was stormed and occupied on 15 April 2023 during the Battle of Khartoum.

The current airport is scheduled to be replaced by the New Khartoum International Airport in Omdourman 40 kilometres (25 mi) south of the centre of Khartoum. This is planned to have two 4,000 metres (13,000 ft) runways, a passenger terminal of 86,000 m2 (930,000 sq ft) and a 300-room international hotel. Construction is to be carried out by China Harbour Engineering Co. (CHEC). On 4 March 2021, the airport's ICAO code was changed from HSSS to HSSK.

The current airport originated as the Royal Air Force airfield Gordon's Tree. By January 1940, No. 223 Squadron RAF was located at Gordon's Tree, in the south of Khartoum.
