'''''Anisonema''''' is a genus of colorless [[flagellate]]s that occur in marine, brackish, and freshwater habitats.{{r|phycokey}} The cell is typically ovoid, somewhat flattened, and rigid.{{r|world}} The name ''Anisonema'' derives from [[Greek language|Greek]] for "unequal thread", in reference to the two [[flagella]] that are of unequal lengths.{{r|phycokey}} The shorter flagellum extends forwards and propels movement with a sweeping motion, while the longer flagellum, up to three times the length of the cell, trails behind, with jerking contractions.{{r|phycokey|world|dujard1841}}

The genus was first named by French biologist [[Félix Dujardin]] his 1841 ''Histoire naturelle des zoophytes. Infusoires, comprenant la physiologie et la classification de ces animaux, et la manière de les étudier à l'aide du microscope''.{{r|dujard1841}}

{{As of|2020}}, there are around 20 accepted species in the genus.{{r|algaebase}}
