Lithodes maja is a species of king crab which occurs in the colder waters of Europe and North America. It is found along entire coast of Norway [2], the northern half of the British Isles, and around the Faroe Islands, Iceland, Svalbard and off south-eastern Greenland [1]. In Canada, it is found from Newfoundland southwards [3].

The carapace is almost circular and may reach a width of 13–14 cm [2]. The whole body is brown or orange and is covered with large spikes. It lives on both soft and hard bottoms, from a few metres below the surface to around 800 m depth [2][1]. Like most king crabs, females are asymmetrical, with the left side of the abdomen considerably larger than the right, although specimens with the reverse of this are occasionally found [4].

The low rate of egg production by this species, in comparison to species fished in the North Pacific, limits its abundance, making it unsuitable for commercial exploitation [5].
