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.

[3][4] There are future plans to transform Seletar into one of the Singapore's regional centres, along with Jurong East, Tampines and Woodlands.

The recent introduction of newer residential property and retail malls, most notably Greenwich V and Seletar Mall,[5] Parc Botannia at Fernvale, Luxus Hill, Belgravia Ace[6] and Parc Greenwich has served well in rejuvenating the Seletar area, with further plans to increase BTO flats supply in the area serve to create additional housing options for people working in the Aerospace Park.

It includes the areas covering Yio Chu Kang, Jalan Kayu, Lower Seletar Reservoir and a part of Upper Thomson.
