Dr. Vincent Wijeysingha (born 1970) is an academic, civil activist and politician from Singapore. He was a member of the opposition Singapore Democratic Party (SDP) 2010 to 2013. He served as the party's Treasurer and stood as a parliamentary candidate for the party 2011 general election. He was Singapore's first openly gay politician.
Dr Wijeysingha has served as the Executive Director of Transient Workers Count Too (TWC2), a non-government organisation advocating the rights of low-waged migrant workers. He also publishes scholarly papers on social work and has worked as a lecturer in social work at SIM University.
Dr Wijeysingha has stated that he joined the SDP because he realised he had a responsibility as a Singaporean to work for change, saying that: "I cannot look the other way as more and more people experience the adverse effects of current PAP policies."
Prior to the 2011 general election, Channel NewsAsia invited the main political parties in Singapore to record an hour-long televised pre-election forum (the first forum of this nature in Singapore since the 1988 general election). The programme, in English entitled, A political forum on Singapore's future, brought together the ruling People's Action Party (PAP) and four opposition parties to discuss long and short-term challenges for the country. Dr Wijeysingha represented the SDP in the discussion.
Just days before Nomination Day on 27 April 2011, the PAP team in the Holland-Bukit Timah Group Representation Constituency (GRC) led by Dr Vivian Balakrishnan, told the press that the SDP was "suppressing" a video which would "raise some awkward questions" about the party's agenda. Dr Wijeysingha's response was that he was unsure about which video Dr Balakrishnan was referring to and that the SDP was "an open party".
