Suvarnabhumi Airport (Thai: ท่าอากาศยานสุวรรณภูมิ; RTGS: Suwannaphum; pronounced [sù.wān.ná.pʰūːm] (Thai pronunciation); from Sanskrit, सुवर्णभूमि, "Golden Land")

The airport is located in Racha Thewa in Bang Phli, Samut Prakan, about 25 kilometres (16 mi) east of downtown Bangkok. The name Suvarnabhumi was chosen by King Bhumibol Adulyadej and refers to the golden kingdom hypothesised to have been located somewhere in Southeast Asia.

The building was designed by Helmut Jahn of Murphy / Jahn Architects. It was constructed primarily by ITO JV. The airport has the world's tallest free-standing control tower (132.2 metres or 434 feet), and the world's fourth largest single-building airport terminal (563,000 square metres or 6,060,000 square feet).
