The Tasmanian Government Railways DP class was a class of diesel railcars operated by the Tasmanian Government Railways.

The DP class diesel railcars comprised eight different batches of vehicles.

The early members were originally petrol powered wooden bodied rail motors while the latter units were articulated units.

These latter units were initially used on the Tasman Limited when it was introduced in April 1954 until locomotive hauled stock was built.

One was retained until 1996 as a track inspection vehicle.
