The Crystal Mover is an automated people mover (APM) system for airport and light rail applications manufactured by Mitsubishi Heavy Industries. The Crystal Mover is based on the Japanese APM standard, used in six Japanese light rail systems including the Yurikamome and the Rokko Island Line.

In Singapore, Crystal Movers operate on the Sengkang LRT Line and the Punggol LRT Line lines. These cars have been operating since 2002 on the Sengkang LRT for testing and on the Punggol LRT since its operation in 2005. These cars have similar features to the Bombardier Innovia APM 100, but with a more futuristic design (as required by the Land Transport Authority) to complement the futuristic new towns of Sengkang and Punggol. There is a fleet of 41 cars in total for the two LRT lines.
