Sagmariasus verreauxi is a species of spiny lobster that lives around northern New Zealand, the Kermadec Islands the Chatham Islands and Australia from Queensland to Tasmania.

[3] It is probably the longest decapod crustacean in the world, alongside the American lobster Homarus americanus, growing to lengths of up to 60 centimetres (24 in).

[2] S. verreauxi was formerly included in the genus Jasus, but has been separated into a monotypic genus Sagmariasus due to the lack of sculpturation on the abdomen, which is found in all other Jasus species.

[3] During the early 20th Century, Sagmariasus verrauxi and Jasus edwardsii were one of the cheapest seafoods in New Zealand, with European New Zealanders preferring the taste of British crayfish, Austropotamobius pallipes.

Large hauls of Sagmariasus verrauxi were harvested in Northland, either sold cheaply or used as chickenfeed.
