2011 Singaporean presidential election

Presidential elections were held in Singapore on 27 August 2011. Incumbent president S. R. Nathan, who had been elected unopposed in 1999 and 2005, did not seek re-election. It was the fourth direct presidential election and the second to be contested by more than one candidate.

Four candidates contested the non-partisan position: Tony Tan, Tan Cheng Bock, Tan Jee Say and Tan Kin Lian. All were independents or had resigned from any political parties they were previously members of. Each candidate was issued a Certificate of Eligibility (COE) and a community certificate, meeting the eligibility requirements to contest in the election.

Singaporeans were unusually divided in this election. Tony Tan won with 35.20% of the vote, narrowly defeating Tan Cheng Bock, who received 34.85%, by just 7,382 votes, prompting an election recount. The other candidates, Tan Jee Say and Tan Kin Lian, received 25.04% and 4.91%, with Tan Kin Lian losing his election deposit for failing to secure over 12.5%. As no runoff elections apply for less than 50% of the vote, Tan was inaugurated as the seventh President of Singapore on 1 September 2011 with a relative majority result.
