The New Zealand DSC class locomotive is a heavy shunting locomotive used throughout New Zealand. The class was built in seven batches, the first 18 locomotives being built by British Thomson-Houston of the United Kingdom, with the further 52 locomotives being built by New Zealand Railways (NZR).

The class is widely used in both the North and South Islands of New Zealand, mainly for heavy yard shunting, although some members of the class have been used for local mainline shunting services. All remaining members of the class are now fitted with shunters refuges, and most are fitted with remote control capabilities.
