The Airport Rail Link (ARL) (Thai: รถไฟฟ้าแอร์พอร์ต เรล ลิงก์) is an airport rail link line in Bangkok Metropolitan Region connecting Suvarnabhumi Airport to the city center. The commuter rail line starts at the underground platforms inside Suvarnabhumi station, before ascending onto an elevated viaduct to Lat Krabang station, and continuing west parallel to the eastern line railway. It intersects with Yellow Line and Blue Line before terminating at Phaya Thai station where it meets Sukhumvit Line. It is owned by State Railway of Thailand (SRT) and, since 2021, operated by Asia Era One Company Limited. The 28.6-kilometer (17.8 mi)-long Airport Rail Link opened for service on 23 August 2010.

In the future, Airport Rail Link will extend from Phaya Thai towards Krung Thep Aphiwat Central Terminal and Don Mueang International Airport. Its rail will also be used for the proposed Don Mueang–Suvarnabhumi–U-Tapao high-speed railway.
