The New Zealand DSG class is a type of diesel-electric shunting locomotive used in New Zealand. The class shares a central cab design with the smaller DSC class shunting locomotive, and is twin-engined. Meanwhile, the very similarly designed, single-engined DSJ class, has a cab that is offset from the centre.

The DSG class shunters were built in four batches from 1981 to 1983 and have seen widespread use throughout New Zealand, particularly in larger yards and for port traffic. They also see service on sections of mainline, performing regional shunt duties in a number of areas.
