As a part of ecological survey of Dokdo Islands, Korea the hydroid collections were made in its intertidal and subtidal zones by the one of present authors and others during the periods from March 1993 to May 1999. The specimens were identified into 15 species of 11 families (Corymorphidae, Corynidae, Eudendriidae, Solanderiidae, Boungainvilliidae Tubulariidae, Lafoeidae, Haleciidae, Campanulariidae, Sertulariidae and Pulmulariidae) in two orders (Athecatae and Thecatae). Two species of them, Fukaurahydra anthoformis (Corymorphidae) and Rhizorhagium sagamiense (Bougainvilliidae) were turned out to be new to the Korean fauna.
