Tengah /ˈtəŋɑː/ is a planning area and HDB town located within the West Region of Singapore.

In late 2018, massive construction works for the HDB estates started in Tengah C1 and C2 planning areas, which are estimated to be completed by 2025.

[8] Tengah was also marketed as Singapore's first smart and sustainable town with a centralised cooling system, which is managed by national grid operator SP Group.

[4] Various types of dense vegetation are planted along roads to serve as noise and visual barriers, providing a cleaner, greener living environment.

Eco-friendly features in Tengah include bioswales and bioretention basins (or rain gardens), which will collect and cleanse the rainwater before it is stored for reuse within the development or channelled into reservoirs.

Such water features also create a conducive habitat for dragonflies and amphibians, which add to the biodiversity of the town and help promote a healthy ecological balance.

All roads in Tengah, with the exception of Plantation Crescent due to JRL construction, are required to have a bus lane.

[13] Tengah Boulevard will be connected to the eastbound direction of the Pan Island Expressway via slip roads from 5 October 2024.

[4] The bigger part of the former Hong Kah Village was an SAF military training area until 10 November 2015.
