Sir Seewoosagur Ramgoolam International Airport (IATA: MRU, ICAO: FIMP) is the main international airport in Mauritius. It is located 26 nautical miles (48 km) southeast of the capital city of Port Louis. The airport was previously known as the Plaisance Airport and has direct flights to several destinations in Africa, Asia, Europe and is home to the country's national airline Air Mauritius. Airports of Mauritius Co. Ltd (AML) is the owner and operator of the airport, the Government of Mauritius is the major shareholder of AML.

A new passenger terminal was inaugurated on 30 August 2013, and became fully operational in September 2013. The structure of the New Airport Terminal is designed after the "Traveller's palm", a tropical plant that grows on Mauritius. It is connected to the existing terminal (refurbishment began in 2014) and has a capacity of 4 million passengers. Airport Terminal Operations Ltd (ATOL) is responsible for the design, building and operation of the new terminal building.

The new terminal, which cost US$306 million, is in line with the "Maurice Ile Durable" concept. Environmental and ecological aspects taken into consideration include using solar energy collected by photovoltaic cells, recovering rain water, integrating nature to the heart of the building, and including thermo-insulated facades to reduce heat gain. The terminal covers an area of 57,000 square meters and is equipped with five boarding gates with airbridges, including one compatible with the large Airbus A380, check-in desks for departing passengers, immigration counters, and baggage carousels.
