The New Zealand DSJ class is a class of diesel-electric shunting locomotive used on the New Zealand rail network. The class has a very similar overall design to the DSG class, but is instead single-engined, has a cab that is offset from the centre, and is both shorter and lighter than its twin-engined counterpart. The first DSJ was assembled in Japan by Toshiba Heavy Industries, the same company who built the EO class electric locomotives. The remaining four were assembled at the former Addington Workshops in Christchurch.

With only 5 members in this class, it represents one of the smallest contingents of shunt locomotives in current use.
