Kallang Airport (also known as the Kallang Aerodrome, Kallang Airfield and RAF Kallang) was the first purpose-built civil international airport in Singapore. It was officially opened on 12 June 1937 and was closed in 1955, when its operations were relocated to Paya Lebar. At its greatest extent, the airport, which was situated on the eastern shore of the Kallang Basin, spanned the modern planning areas of Kallang and Geylang. The conserved remains of the airport, including its terminal building, are located wholly within Kallang.

Boasting an anchorage area for seaplanes along the airport's perimeter on the Kallang Basin, the Kallang Airport was hailed as "the finest airport in the British Empire" at that time. Famous aviator Amelia Earhart once described it as "an aviation miracle of the East".

Construction of the Kallang Airport began in 1931 with 300 acres (120 ha) of mangrove swampland being reclaimed. It resulted in the displacement of a large Malay community to the area around Jalan Eunos. Three Hawker Osprey aircraft first touched down in the Kallang Airport around two years before its official opening, on 21 November 1935. During World War II, the Kallang Airport was the only operational airfield in Singapore capable of supporting Allied campaigns against the Japanese forces.
