Tampines Group Representation Constituency

The electoral boundaries remained unchanged between the 2001 elections until early 2020 when its boundaries were redrawn to include Tampines retail park from the neighbouring Pasir Ris–Punggol GRC. The GRC has faced a contest in every general election except 1997, in which the National Solidarity Party was disqualified. In the 2001 and 2006 general elections, the PAP's opponent was the Singapore Democratic Alliance (due to a merger with National Solidarity Party until 2007).

Following the 2020 EBRC redrawn exercise, the constituency has brought in places that include the Tampines Wafer Fab Park and the entire Tampines North Industrial Estate comprises locations such as Giant Hypermart and IKEA Tampines.

Previously, ex-Minister for National Development Mah Bow Tan was the anchor minister until he stepped down from the cabinet following the 2011 general elections, retiring from politics in 2015. In May 2016, Heng Swee Keat was incapacitated due to a stroke. His condition was reported to be stable but he remained in the hospital's intensive care unit until 25 June 2016. His fellow MPs assisted to oversee his Tampines Central ward with the former MP Sin Boon Ann returning to help until his discharge. Heng Swee Keat was the anchor minister until he was transferred to nearby East Coast GRC in 2020; he was succeeded by Koh Poh Koon.

Tampines Town Council is operating under Tampines GRC.

^ Pior to the 2020 Singaporean general election, Heng Swee Keat was transferred to East Coast GRC and was succeeded by Koh Poh Koon.
