Anson Constituency was a constituency in Singapore. It used to exist from 1959 to 1988 and was merged into Tiong Bahru Group Representation Constituency in 1988.

In 1981, incumbent MP Devan Nair resigned from the PAP and the Parliament to accept the then largely ceremonial office of President as the country's head of state.^[1] This resulted in the third time Anson had a by-election. Nominations for the by-election started on 21 October. Three candidates were nominated for the by-election: PAP had Pang Kim Hin, the nephew of former minister Lim Kim San; Workers' Party (WP) secretary-general J.B. Jeyaretnam; and United People's Front Harbans Singh. Chiam See Tong, who recently founded Singapore Democratic Party (SDP) a year prior to the by-election, expressed interest but withdrew later and backed Jeyaretnam.

The by-election was eventually won by Jeyaretnam of WP, the first time in Singapore since 1963 when a party candidate not from the PAP had won a parliamentary seat.^[2]

In 1988, the constituency was dissolved following the establishment of Group representation constituency (GRC) and Single Member Consituency (SMC).^[3]

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%.
