The Bukit Panjang Single Member Constituency is a Single Member Constituency (SMC) located in the north–western area of Singapore. The current Member of Parliament for the constituency is Liang Eng Hwa from the People's Action Party (PAP). One of Singapore's oldest constituencies, it was originally known as Bukit Panjang Constituency from 1955 until 1988, when it was renamed following the introduction of the Group Representation Constituency (GRC) system at the 1988 general election. The constituency was abolished at the 1991 general election but was re-established in the 2006 general election, and has been contested in every general election since. It is managed by the Holland–Bukit Panjang Town Council (HBPTC).

The constituency was first established for the 1955 general election and was won by Goh Tong Liang of the Progressive Party (PP), who defeated Lim Wee Toh of the Labour Front (LF). At the 1959 general election, Lee Khoon Choy of the People's Action Party (PAP) secured the seat in a four-cornered contest against candidates from the Liberal Socialist Party (LSP), the Singapore People's Alliance (SPA) and the Malayan Indian Congress (MIC), receiving 58.14 percent of the vote. In the 1963 general election, the PAP lost the constituency to Barisan Sosialis (BS), its breakaway left-wing faction. The seat was won by Ong Lian Teng of BS, father of PAP politician Ong Ye Kung.^[1] The PAP regained control of the constituency at the 1967 by-election after BS members resigned from Parliament as part of a boycott against the legitimacy of the PAP government in post-independence Singapore.

P. Selvadurai represented the constituency until the 1972 general election, when he was fielded in Kuo Chuan Constituency and replaced by Lee Yiok Seng in Bukit Panjang. Lee won the seat with 67.65 percent of the vote against Workers' Party (WP) candidate Tang Song Khiang and United National Front (UNF) candidate Leyu Tan Jib, who polled 24.82 percent and 7.53 percent respectively. At the 1988 general election, following the introduction of Group Representation Constituencies (GRCs), the seat was renamed Bukit Panjang Single Member Constituency in line with the new designation for constituencies with only one Member of Parliament.^[2] Lee remained MP until the seat was absorbed into the Sembawang Group Representation Constituency (GRC) in the 1991 general election.

From 1991 to 2006, the constituency remained part of Sembawang GRC. It was reconstituted in the electoral boundary review for the 2006 general election, formed from portions of Holland–Bukit Panjang GRC, which had absorbed the ward in the 2001 general election.^[3] Holland–Bukit Panjang GRC was dissolved at the same time.

Ahead of the 2020 Singapore general election, incumbent PAP MP Teo Ho Pin announced his retirement from politics.^[4] Liang Eng Hwa, formerly MP for Holland–Bukit Timah GRC, was introduced as the PAP candidate. The Singapore Democratic Party (SDP) fielded Paul Tambyah as its candidate.^[5] Liang won the contest with 53.74 percent of the vote, defeating Tambyah which got 46.27 percent and by a margin of 2,509 votes.^[5] In March 2025, it was confirmed that Liang and Tambyah would rematch at Bukit Panjang again in the 2025 general election.^[6] Liang retained the seat with an increased vote share of 61.41 percent, reflecting a broader national swing in favour of the PAP.^[7][8]

Note : Elections Department Singapore do not include rejected votes for calculation of candidate's vote share. Hence, the total of all candidates' vote share will be 100%.
