KTM Intercity () are diesel-hauled intercity train services in Peninsular Malaysia and Singapore, operated by Keretapi Tanah Melayu Berhad (KTMB). Services operate along the East Coast Line between Tumpat and Gemas and on towards Singapore on the West Coast Line. The former Intercity services along the West Coast Line between Padang Besar in the north (and subsequent services to Thailand) and Gemas have been converted to the KTM ETS service (except for the small portion of the line between Pulau Sebang/Tampin and Gemas which is currently served by both train services).
