The 2800 Class is a type of diesel multiple unit operated on the Irish railway network by Iarnród Éireann, used mainly for short-haul InterCity and Commuter services.

The 2800 Class were built in Japan by Tokyu Car Corporation.

Like the 2600, 2700 and 2750 Classes, they were delivered in "Arrow" livery, however the Arrow logo was removed shortly after they entered service and replaced with the National Development Plan logo.

The 2800 Class were the first Irish trains to be fitted with PA systems which included both on-board announcements and message boards at either end of the coach.

Because of their design, which allows movement between sets of multiple units working together, they were used on Rosslare line InterCity services where it was possible to run a minimal catering service on the line using these units.
