Hexabothriidae is a family of monogenean parasites. The family name was proposed by Emmett W. Price in 1942. The family includes 14-16 genera according to authors and about 60 species; all are parasitic on the gills of chondrichthyan fishes (rays, sharks and chimaeras).
Studies on phylogeny of monogeneans based on morphology, molecules or spermatozoa suggest that the Hexabothriidae are a basal group within the Polyopisthocotylea.
