Te stylasterid fauna of Alaska is revised, consisting of the description or redescription and illustration of 21 species, one additional infspecies, and a geographically adjacent species: Stylaster venustus. Six new species and one new infspecies are described: Errinopora fsheri, E. undulata, E. disticha, E. dichotoma, Stylaster crassiseptum, S. repandus, and Stylaster parageus columbiensis. Four infspecies are raised to species rank: Stylaster leptostylus, S. trachystomus, S. parageus, and Distichopora japonica, and fve species and one infspecies were synonymized. A dichotomous key to the Errinopora species and tabular keys to the Errino-pora and Alaskan Stylaster species are provided. Te focus of the study was on the stylasterids from Alaska, primarily those from the diverse Aleutian Islands, but also including records from British Columbia. Tis is the frst revisionary work on this fauna since the seminal report by Fisher in 1938. © S.D. Cairns, A. Lindner.
