The scorpionfishes of Korea are composed of 30 species in 8 genera, and the keys to species and genera are provided with svnonvms and their distributions. Four species newly reported from Korea are redescribed and figured: Sebastiscus tenius (Barsukov et Chen), Sebastes steindachneri Hilgendorf, S. minor Barsukov and S. zonatus Chen et Barsukov. It is noted that the genus Sebastes comprise 18 species in Korean waters without endemics. Most species of the Korean scorrionfishes are shared with Japanese and Taiwanese faunas including temperate and tropical scorpionfishes. Most Sebastes species are recognized as temperate elements but other genera of this family are regarded as tropical elements.
