Seletar is an area located in the north-east of Singapore. Its name can also refer to the Seletar Planning Area (as defined by the Urban Redevelopment Authority), situated in the North-East Region of Singapore. It shares boundaries with the planning areas of Sengkang to the south, Punggol to the east, Yishun and Simpang to the west, as well as the Straits of Johor to the north.

The aerospace park is expected to be completed in 2018 and will house industries specialising in aircraft maintenance and repair services. There are future plans to transform Seletar into one of the Singapore's regional centres, along with Jurong East, Tampines and Woodlands.
