The British Rail Class 756 FLIRT is a class of tri-mode multiple units built for Transport for Wales Rail by Swiss rolling stock manufacturer Stadler Rail. They are closely related to the Class 755 bi-mode units delivered by Stadler to Greater Anglia between 2018 and 2020, which can be powered either by overhead electric lines or on-board diesel generators. The Class 756 units also carry batteries as an additional source of traction power.

A total of 24 units were built, split between 7 three-car units and 17 four-car units.
