The KLIA T1 1 ERL station (formerly known as KLIA) is a station on the Express Rail Link (ERL) which serves the Terminal 1 building of Kuala Lumpur International Airport (KLIA) in Sepang, Selangor, Malaysia. The station is located on the first floor of the building. It is served by both lines of the ERL, the KLIA Ekspres and KLIA Transit.

All ERL trains stop at this station and the KLIA T2 ERL station. The KLIA Ekspres runs non-stop to KL Sentral, the main railway in the capital Kuala Lumpur, while the KLIA Transit makes additional stops at three intermediate stations before terminating at KL Sentral.

The KLIA Ekspres and KLIA Transit services each operate on two 2 km bi-directional single tracks between the Terminal 1 and Terminal 2 stations. The KLIA Ekspres runs on the track connecting Platforms A of both stations and the KLIA Transit between Platforms B respectively. Passengers are advised whether a service is inbound or outbound through automated station announcements and platform displays.

These overlapping services and shared stations allow the ERL to function as a higher frequency shuttle between Terminal 1 and Terminal 2 unlike the termini at KL Sentral where the services end and start at their separate platforms on different corners of the station.
