Tampines Single Member Constituency (Traditional Chinese: 淡濱尼單選區; Simplified Chinese: 淡滨尼单选区) is a former single member constituency in Tampines, Singapore and is one of the oldest wards. It existed from 1959 to 1988.
In the 1955 general elections, this ward started as part of Punggol-Tampines SMC which consisted of largely present-day Hougang, Pasir Ris, Punggol, Sengkang, Simei and Tampines. These were considered rural areas of Singapore and had a very low population (there were only 6,628 voters then, of which only 3,886 of them turned out to vote).
Subsequently in 1959, this ward was split into Punggol SMC and Tampines SMC. The present-day Hougang, Punggol and Sengkang were hived off as Punggol SMC while Tampines SMC took on significant portions of Ulu Bedok SMC to become one of the larger wards in eastern Singapore. Thus, Tampines SMC was made up of present-day Bedok (except Kampong Chai Chee which is part of the Kampong Kembangan SMC), Pasir Ris, Simei, Tampines. It remained thus until 1968 when Bedok was largely transferred to Kampong Chai Chee SMC.
