2006 Singaporean general election

General elections were held in Singapore on 6 May 2006 to elect members of Parliament. They were the twelfth general elections since the introduction of self-government in 1959 and the tenth since independence in 1965. President S.R. Nathan dissolved parliament on 20 April on the advice of Prime Minister Lee Hsien Loong three weeks before the election. Despite changes to electoral boundaries, the number of elected seats had remained unchanged at 84 from the previous election. This was the first election contested by Lee as prime minister, following his succession of Goh Chok Tong in 2004.

The ruling People's Action Party (PAP) achieved a landslide victory in the election, retaining its supermajority by winning all but two of the 84 parliamentary seats. However, its overall share of the popular vote fell to 67%. While they secured 37 seats uncontested on nomination day, this marked the first time since 1988 that the PAP was not returned to power by then. It was also the first election since 1968 in which every contest was a direct head-to-head race and the only one where no losing candidate forfeited their election deposit. This election was also notable for being the first to introduce overseas voting at selected Singaporean diplomatic missions.

Key issues in the election included employment, the rising cost of living, housing, transport, education, the need for an effective opposition presence in parliament and the overall quality of candidates. It was also the first election in which the internet played a significant role in campaigning among the general public. As of 2025, it remains the most recent election in which two opposition parties succeeded in electing at least one candidate in a constituency that excluded non-constituency seats (NCMPs) as well as the last election in which the ruling PAP won every group representation constituencies (GRCs).
