Holland-Bukit Timah Group Representation Constituency

Holland-Bukit Timah Group Representation Constituency (荷兰-武吉知马集选区; Kawasan Undi Perwakilan Berkumpulan Holland-Bukit Timah; ஹோலண்ட்-புக்கிட் தீமா குழுத்தொகுதி) is a four-member Group Representation Constituency located in the central, western and northern areas of Singapore. The Group Representation Constituency has received two contests since 2011, which is the former presidential candidate and now the SingFirst secretary-general Tan Jee Say in 2011 and the current SDP secretary-general Chee Soon Juan in 2015 who was being sued for defamation, both of which were contested under Singapore Democratic Party.

Originally known as the Holland-Bukit Panjang Group Representation Constituency, it was renamed to its present name due to the Bukit Panjang ward of the GRC being carved out to form a Single Member Constituency, in return the Bukit Timah Single Member Constituency was absorbed. A large portion of Holland-Bukit Timah GRC is made up of jungle and nature reserve, namely the Bukit Timah Nature Reserve and the Central Water Catchment.

Holland-Bukit Timah GRC is led by Minister for Foreign Affairs Dr Vivian Balakrishnan and Senior Minister of State Sim Ann.
