Cheng San GRC

Cheng San Group Representation Constituency (Simplified Chinese: 静山集选区;Traditional Chinese: 靜山集選區) is a now defunct Group Representation Constituency in the north-eastern region in Singapore. The GRC consisted of the eastern part of Ang Mo Kio, Jalan Kayu, Seletar Hills, part of Serangoon North, a large part of Hougang, Buangkok, and the whole of Sengkang New Town and Punggol New Town.

The GRC was formed in 1988, and absorbed the constituencies of Cheng San, Chong Boon and Jalan Kayu. In the 1991 general election, the constituency was enlarged to include the former Punggol ward. For the general election in 1997, parts of the Chong Boon division of the GRC, bounded by Ang Mo Kio Avenue 10, Ang Mo Kio Avenue 3, Central Expressway and Ang Mo Kio Avenue 1, were transferred to Ang Mo Kio GRC. The GRC was an opposition favourite in the 1991 election, and was hotly contested in the 1997 general election between People's Action Party and Workers' Party. The Punggol constituencies were split into Punggol Central, Punggol East and Punggol South as a result of the growing population of Hougang to encourage attacking the population of Sengkang and Punggol which was ready since 1999 and it necessitated the redrawing. The GRC was absorbed into three GRCs in the 2001 general election. The GRCs which absorbed Cheng San GRC were Ang Mo Kio GRC, Pasir Ris-Punggol GRC and Aljunied GRC due to redrawing of electoral districts by the Elections Department.
