Bukit Panjang, often abbreviated as Bt Panjang or simply BP, is a planning area and residential town located in the West Region of Singapore. The planning area is bounded by Bukit Batok to the west, Choa Chu Kang to the northwest, Sungei Kadut to the north, the Central Water Catchment to the east and Bukit Timah to the south. Bukit Panjang New Town is located at the northern portion of the planning area. Bukit Panjang has an average elevation of 36m/118 ft and a portion of this town is situated on a low-lying elongated hill.
The town is categorised into seven subzones, namely Jelebu, Bangkit, Fajar, Saujana, Senja, Dairy Farm and Nature Reserve.
Bukit Panjang is a quieter town compared to some of the older housing estates such as Toa Payoh, Ang Mo Kio and other more publicly discussed towns due to its lower population, but it has seen major developments in recent years.
