Calliotropis regalis, or the "regal spiny margarite",[3] is a species of sea snail, a marine gastropod mollusk in the family Calliotropidae.[2]

In older literature, this species was always synonymized with Margarita regalis Verril & Smlith, 1880 or with Trochus ottoi Philippi, 1844 or with Solariella ottoi Philippi, 1844, all synonyms of Calliotropis ottoi (Philippi, 1844).


The size of an adult shell varies between 6 mm and 18 mm.


This species is distributed in European waters along the British Isles and the Faroes, in the Mediterranean Sea, in the Northwest Atlantic Ocean from Nova Scotia to North Carolina.
