The status of Indo-Pacific Briareum species (Cnidaria, Octocorallia, Briareidae) is reviewed by presenting their sclerite features and habitus descriptions. Following the re-examination of type material, museum specimens and newly collected specimens, a species identification key is provided. The species distributions are discussed and updated distribution ranges are depicted. Moreover, a new taxon, Briareum
cylindrum
sp. n. is described and depicted, whereas Briareum
excavatum (Nutting, 1911) is synonymised with Briareum
stechei (Kükenthal, 1908). Briareum
hamrum (Gohar, 1948) is recorded from the Persian Gulf and Oman Sea for the first time. Consequently, in total four Briareum species are recognized in the Indo-Pacific; Briareum
hamrum from the western Indian Ocean, and Briareum
cylindrum
sp. n., Briareum
stechei, and Briareum
violaceum from the central and eastern Indo-Pacific region.
