This paper is a contribution to the study of the family Polynoidae (Polychaeta) from the Canary Islands. The material examined has been collected by the authors from 1975 to 1989. A total of 18 species was found belonging to 8 genera: Gesiella (1), Polynoe (1), Adyte (1), Subadyte (1), Harmothoe (11), Alentia (1), Lepidasthenia (1) and Lepidonotus (1). Ten species are new to this fauna and one, Harmothoe cascabullicola, is new to science. Furthermore, the genera Polynoe, Adyte and Lepidasthenia are recorded for the first time in the Canary Islands.
