Segambut (Chinese:泗岩沫)is a sub-district and a parliamentary constituency in Kuala Lumpur, Malaysia.
From the high-end condominiums of Mont Kiara and Sri Kiara to the middle-class areas of Taman Sri Segambut and Bandar Manjalara, and the rural areas of Segambut Dalam and Kampung Sungai Penchala, the Segambut constituency has a diverse population base.
Segambut once belonged to the mukim of Batu Caves before 1974, when Kuala Lumpur was still part of Selangor.
The constituency was created in 1994 and has been considered to be a Barisan Nasional safe seat until the 2008 General Elections. Datuk Dr Tan Kee Kwong of Parti Gerakan Rakyat Malaysia (Gerakan) had won the seat the last three terms. However, in the 2008 General Elections, Lim Lip Eng from the Democratic Action Party (DAP) won the seat.
There are a total of 59,690 voters in the constituency, of which almost half are ethnic Chinese. Areas like Taman Bukit Maluri and Taman Sri Sinar have a high percentage of Chinese voters while areas like Segambut and Taman Bunga, Malay.
Segambut is served by the train station of the same name, on the KTM Komuter line, that runs from Tanjong Malim to Port Klang, via KL Sentral and other city-centre stations.
The new Istana Negara is located in this constituency, along Jalan Tuanku Abdul Halim (fka Jalan Duta).
