The Bishan–Toa Payoh Group Representation Constituency (GRC) is a four-member Group Representation Constituency located in the central region of Singapore. There are four divisions of the GRC: Bishan East–Sin Ming, Toa Payoh West–Thomson, Toa Payoh East and Toa Payoh Central, managed by Bishan–Toa Payoh Town Council. The current Member of Parliament (MP) are Cai Yinzhou, Chee Hong Tat, Elysa Chen and Saktiandi Supaat, from the People's Action Party (PAP).

History

The GRC was formed prior to the 1997 general election with five seats; the PAP won uncontested. Ho and Ibrahim retired from politics during the 2001 general election with Zainudin Nordin and Ng Eng Hen replacing them. The GRC was uncontested again. In 2006, Leong and Davinder retired from politics and was replaced with Hri Kumar Nair and Josephine Teo. The GRC was uncontested for the third time.

During the 2011 general election, Chiam See Tong, the leader of the Singapore People's Party (SPP), left his stronghold of Potong Pasir Single Member Constituency (SMC) to lead a team of five in Bishan–Toa Payoh GRC. Led by Wong Kan Seng, the unchanged PAP team retained the GRC with 56.93% of the vote.

The GRC's boundaries remained intact since its formation until 2015 when it was expanded in size to include Balestier, MacRitchie Reservoir and Novena. The westernmost portion of Bishan–Toa Payoh GRC consists of part of the Central Catchment Nature Reserve which is shared with Holland–Bukit Timah GRC and Kebun Baru SMC.

Before the 2015 general election, Wong, Nair and Zainudin retired from politics with the latter two for personal reasons. SPP contested the GRC against the PAP team with Ng Eng Hen leading the team. The PAP team won the elections consecutively for the second time with the results of 73.59%.

During the 2020 general election, Balestier and Novena was subsumed into the neighbouring Jalan Besar GRC. Some residential areas in Potong Pasir SMC were absorbed into Toa Payoh East. Bishan North and Shunfu was carved out and was absorbed into the new Marymount SMC. The GRC was reduced to four. Josephine Teo left the GRC to lead the PAP team for Jalan Besar GRC.

The SPP contested the GRC again and only managed to gain 32.74% of the votes while the PAP team won the elections again for third time consecutively with the results of 67.26%.

During the 2025 general election, incumbent MPs Ng Eng Hen and Chong Kee Hiong announced their retirement from politics.^[1]^[2] Chee Hong Tat became the new PAP anchor minister, with Saktiandi Supaat remaining and two new candidates Cai Yinzhou and Elysa Chen joining the team to contest the GRC against a SPP team led by Steve Chia.^[1]^[3] The PAP team won the contest with 75 percent of the vote.^[4]
