Suvarnabhumi Airport (IATA: BKK, ICAO: VTBS), also known as (New) Bangkok International Airport, is the international airport serving Bangkok, Thailand. After delays and three decades of planning, the airport opened for limited domestic flight service on 15 September 2006, and opened for all domestic and international commercial flights on 28 September.

The airport is located in Racha Thewa in Bang Phli district, Samut Prakan Province, about 25 km east of downtown Bangkok. The name Suvarnabhumi was chosen by King Bhumibol Adulyadej and refers to the golden kingdom hypothesized to have been located somewhere in Southeast Asia. Designed by Helmut Jahn of Murphy/Jahn Architects, this airport has the world's tallest control tower (132.2 m), and the world's third largest single-building airport terminal (563,000 m²). Suvarnabhumi is one of the busiest airports in Asia and Bangkok's primary airport for all international airline flights. The airport inherited the airport code BKK from Don Mueang after the older airport ceased commercial flights. A modern motorway connects the airport, Bangkok, and the heavily industrial Eastern Seaboard of Thailand, where most of the manufacturing for export takes place.
