In 1951, the Tanglin Constituency was formed by carving up Municipal South-West Constituency. In 1955, parts of the constituency were divided to form Cairnhill, Havelock and Queenstown constituencies. In 1959, it was further divided to form River Valley and Ulu Pandan constituencies.

In 1988, it was renamed as Tanglin Single Member Constituency as part of Singapore's political reforms. In 1997, it was abolished and merged into Kreta Ayer–Tanglin Group Representation Constituency.
