Avrainvillea is a genus of green algae in the family Dichotomosiphonaceae.
Description Avrainvillea is a green siphonous marine macroalgal species.Lagourgue, L, Rousseau, F, Zubia, M. and Payri, E. 2023. Diversity of the genus Avrainvillea (Dichotomosiphonaceae, Chlorophyta): new insights and eight new species. European Journal of Phycology.58: 399 - 426. In the tropical species the dichotomously and branched filaments are generally united.Fritch, F.E 1965. The Structure and Reproduction of the Algae. Volume 1 p404. Cambridge at the University Press.
Distribution The genus has a worldwide tropical distribution.
Ecology The species occur from the intertidal to 60m.

Avrainvillea erecta was reported to have strong hemagglutination activity.Dinh HL, Hori K, Quang NH. Screening and preliminary characterization of hemagglutinins in Vietnamese marine algae. J Appl Phycol 2009; 21(1): 89-97. In addition, the chloroform fraction of a methanol extract of Avrainvillea erecta exhibited hydrogen peroxide scavenging activity as strong as that shown by gallic acid.Chai TT, Kwek MT, Mohd Ismail NI, Ooi JLS, Yang Amri A, Abd Manan F, Law YC, Wong FC.(2015) Antioxidant activities of methanol extract and solventfractions of marine macroalga, Avrainvillea erecta (Berkeley) A. Gepp and E.S. Gepp (Dichotomosiphonaceae). Tropical Journal of Pharmaceutical Research 14 (3): 503-509.
Eight new species are listed and described.
