The airport began as a Royal Air Force airfield in 1944 during the Second World War, RAF Station Negombo. In 1957, Prime minister S. W. R. D. Bandaranaike removed all the British Military airfields from Ceylon (Sri Lanka), and the airfield was handed over to the Royal Ceylon Air Force (RCyAF) and renamed Katunayake; part of it still remains a military airfield. In 1964 Anil Moonesinghe, the Minister of Communications, started the building of a new international airport to replace Ratmalana, with Canadian aid. The airport was completed in 1967, and Air Ceylon, the national carrier, began international operations from it using a Hawker Siddeley Trident and a leased British Overseas Airways Corporation (BOAC) British Aircraft Corporation (BAC) VC-10. It was named after former Prime Minister SWRD Bandaranaike, in 1970. It was renamed Katunayake International Airport in 1977, but was changed back to Bandaranaike International Airport in 1995.
