Budapest Ferihegy International Airport (Hungarian: Ferihegyi Nemzetközi Repülotér or simply Ferihegy) (IATA: BUD, ICAO: LHBP) is the international airport serving the capital city of Budapest, and the largest of the country's five international airports. The airport offers international connections primarily within Europe, but also to Asia, the Middle East, and North America. In 2007, the airport served 8.6 million passengers.

The airport is located 10 miles (16 km) southeast of the centre of Budapest, accessible by the major transport artery of Ülloi út. Expressway M0 connects all major roads and expressways around the city, reaching the airport and providing faster links to other towns.

The newly opened Terminal 1 serves all low-cost airlines. The terminal was renovated in September 2005. Terminal 2A was built for MALÉV Hungarian Airlines, but it now also serves its code-share airline partners as well. Although connected to Terminal 2A, it is referred to as a separate terminal, opened in 1997. It serves all of the other international flights and airlines not served by Terminal 2A.
