Jalan Kayu SMC

Jalan Kayu Single Member Constituency (Traditional Chinese: 惹蘭加油單選區; Simplified Chinese: 惹兰加油单选区) was a single member constituency in Jalan Kayu, Singapore, between 1959 and 1988.

After the 1951 election, the present Jalan Kayu Single Member Constituency constituted the majority of the Seletar ward; that ward was dissolved prior to the 1959 election, producing the Jalan Kayu ward, the then Thomson ward, and small parts of Nee Soon ward. Following its dissolution in 1988, Jalan Kayu was incorporated into the new Cheng San Group Representation Constituency. The Constituency was a hotly contested ward in the 1997 elections against the Workers' Party, after the People's Action Party had held its predecessor ward by a narrow margin of 571 votes in the 1984 election. Currently, Jalan Kayu took control of Serangoon North HDB estates (Blk 5xx and 6xx), the former ones are Sengkang West.

Cheng San GRC was dissolved prior to the 2001 elections. The ward was then redrawn into Ang Mo Kio Group Representation Constituency, presently held by current Prime Minister Lee Hsien Loong.
