Ratmalana International Airport (Sinhala: රත්මලාන ජාත්‍යන්තර ගුවන්තොටුපළ, romanized: Ratmalāna Jātyantara Guvantoṭupaḷa; Tamil: இரத்மலானை சர்வதேச விமான நிலையம், romanized: Iratmalāṉai Sarvadesa Vimāṉa Nilaiyam) (officially known as Colombo International Airport, Ratmalana and locally as Ratmalana Airport) (IATA: RML, ICAO: VCCC), is the secondary international airport serving the city of Colombo, the capital of Sri Lanka. It was the country's first international airport and was the only international airport in Sri Lanka until the inauguration of Bandaranaike International Airport, Katunayake, in 1967. The airport currently serves several domestic services and is home to several aviation training organisations. A relaxation of rules has recently seen the airport open for international corporate jet operations and charter flights. The airport is located 15 km south of Colombo City.

The strategic significance of Ratmalana International Airport has been identified along with the emerging Colombo Financial City, High End Tourism and business travel needs of High Net Worth Individuals (HNWIs). The long-term strategic goal of RMA is to bring the airport to the optimum operational capacity by maximum utilization of existing resources. Therefore, to achieve this goal, five strategic areas with specific strategies have been identified as Corporate Jet Operations, Domestic Aviation Hub, Aviation Training hub in the Region, FBO & MRO investments and Regional Airports Operations.
