2015 Singaporean general election

General elections were held in Singapore on Friday, 11 September 2015 to elect 89 members of Parliament. The outgoing Parliament had been dissolved and the general election called by President Tony Tan on 25 August, on the advice of Prime Minister Lee Hsien Loong. The elections were for the 13th Parliament since independence in 1965, using the first-past-the-post electoral system.

The elections marked several first since independence: the first election where all seats were contested, including Tanjong Pagar being contested for the first time ever since the ward's formation in 1991. It was also the first election without any original Parliament MPs contesting following the death of the last active MP and the nation's first Prime Minister Lee Kuan Yew in March 2015, coinciding in Singapore's 50th anniversary celebration on 9 August that year. This was the first election (of any kind) in Singapore's history where polling day falls on a Friday instead of the traditional Saturday, and also the first parliamentary election with a reduction of election deposit, down from $16,000 in the last election to $14,500.

Of the 89 seats, most of the seats were contested between two parties, with the only three-cornered fights occurring in three Single Member Constituencies and the presence of independent candidates for the first time since 2001; the People's Action Party (PAP) contested all and won 83, and won its best results since 2001 with 70% of the popular vote, an increase of 10% from the previous elections in 2011, with many constituencies having swings toward PAP island-wide. The other six seats, the five-men Aljunied GRC and Hougang SMC were retained back by the Workers' Party (WP) but however, failed to retain Punggol East SMC after capturing it in a 2013 by-election, thus flipping back to a PAP-state; their vote shares dropped by 7% down to 39.6% of the votes in the 28 seats it contested. In the overall popular vote, WP scored 12.48% and the remaining seven parties less than 4% each.
