Cempaka LRT station is a Malaysian low-rise rapid transit station situated near and named after the nearby Taman Cempaka (Malay; English: Cempaka Estate), in Ampang Jaya, Selangor.

The station is part of the Ampang Line (formerly known as STAR, and the Ampang and Sri Petaling Lines), and was opened on 16 December 1996, as part of the first phase of the STAR system's opening, alongside 13 adjoining stations along the Sultan Ismail-Ampang route.

The Cempaka station is situated east from and named after the Ampang Jaya locality of Taman Cempaka to the southeast, and is within walking distance of Kampung Pandan Dalam (Inner Pandan Village) directly north from the station, Pandan Indah south.

The station was constructed along two leveled tracks, reusing the now defunct Federated Malay States Railway and Malayan Railway route between Kuala Lumpur, Ampang town and Salak South.

(Operated by Smart Selangor) AJ04 also passed by the station by having a stop near Kenari Court Apartment.
