Ulu Bedok Single Member Constituency (Traditional Chinese: 烏魯勿洛單選區; Simplified Chinese: 乌鲁勿洛单选区) is a former short-lived single member constituency in Bedok and Geylang, Singapore that existed only from 1955 to 1959.
In the early days from the 1955, this ward was formed by present-day Bedok, Kembangan and Geylang Serai. The word ulu in Malay means remote, which was very true at that time, the eastern region of Singapore such as Bedok are hilly terrain (Where the hills are later used for reclamation that creates Marine Parade town in the 1970s.) while Hougang, Punggol, Tampines and Pasir Ris were also undeveloped at that time.
Subsequently, in 1959, this ward had split Bedok, Geylang and Kembangan portion. For that, it means the present day equivalent of Geylang Serai was formed as Geylang Serai ward and Kampong Chai Chee along with Kembangan were formed as Kampong Kembangan SMC. The rest of the large ulu Bedok portion was merged into Tampines ward instead and this ward was dissolved since then.
