The Gombak River () is a river which flows through Selangor and Kuala Lumpur in Malaysia. It is a tributary of the Klang River. The confluence where it meets the Klang River is the origin of Kuala Lumpur's name.
Gombak River used to be called the Sungai Lumpur. Kuala Lumpur's name was taken as it was located in Sungai Lumpur's confluence or "Kuala Lumpur".
Malay settlements existed near the Gombak-Klang river confluence since the early 1850s. The river banks were used for growing food and collecting jungle produce. The rivers were used for communication and transportation for the villagers.
