The Changchun EMU or CNR Changchun EMU is an electric multiple unit train type of the Mass Transit Railway (MTR) system in Hong Kong. Designed and manufactured by Changchun Railway Vehicles, a member of CNR group (now merged with CSR to form CRRC), they were the first MTR heavy-rail stock to be manufactured in Mainland China, while past orders came from England, Japan, Europe or South Korea.

The trains come in two versions: the C-Train, a manned eight-car train which is used mainly on the Kwun Tong line;[3] and the S-Train, a driverless three-car variant which operates on the South Island line since its opening in December 2016. Similar trains had been ordered for the Tuen Ma line, also known as TML C-Train, which entered service on the Ma On Shan line on 12 March 2017; however, these trains bear a resemblance to the older SP1900 EMUs.
