1984 Singaporean general election

General elections were held in Singapore on 22 December 1984 to elect members of Parliament. They were the seventh general elections since the introduction of self-government in 1959 and the fifth since independence in 1965. The number of parliamentary seats increased from 75 to 79 following adjustments to electoral boundaries. Out of the 79 constituencies, 49 were contested while the remaining 30 were won uncontested by the People's Action Party (PAP).

Although the entry of an opposition MP in post-independence Singapore first occurred at the 1981 Anson by-election, the 1984 general elections represented a watershed in the nation's political landscape. It was the first occasion since 1963 in which the PAP failed to secure an unbroken sweep of all seats, signalling a departure from its hitherto uninterrupted dominance. Of the 49 seats contested, the Workers' Party (WP) and the Singapore Democratic Party (SDP) won one each, with the WP retaining Anson and the SDP establishing a foothold in Potong Pasir. This election was also the first to introduce the Non-constituency Member of Parliament (NCMP) scheme, which initially provided for three seats. As the opposition secured two elected seats, one NCMP seat was offered, although no opposition member accepted the appointment as the scheme was initially viewed as a token gesture that undermined genuine electoral competition.

The PAP secured 64.83% of the valid votes and 77 of 79 seats, a landslide victory that reaffirmed its supermajority and political dominance. However, it also reflected a sharp 12.83% swing against the party, the largest in any general election to date and marked its lowest vote share since independence. Voter turnout in contested constituencies stood at 95%, remaining largely consistent with the preceding general election. It also marked the returning presence of women candidates since 1970 following the elections of Yu-Foo Yee Shoon, Dixie Tan and Aline Wong from the PAP, who made their debuts this election.
