Monoraphidium is a genus of green algae in the family Selenastraceae.^[1] Monoraphidium is found free-floating or attached to surfaces in water, or in soils.^[2] It is one of the most common types of phytoplankton in freshwater habitats, and has a cosmopolitan distribution.^[3]

Monoraphidium consists of single cells, which are 2-182 by 1-8 micrometers. The cell is straight to lunate to sigmoid or helically shaped. Cells contain a single nucleus, a single parietal chloroplast and a single pyrenoid lacking a starch sheath (or no pyrenoid at all). Reproduction occurs asexually by autospores.^[2]

It is similar to and often confused with the related genus Ankistrodesmus, from which it differs by being typically unicellular.^[4]

Some species and strains of Monoraphidium, such as Monoraphidium neglectum, are promising candidates for commercial biofuel production.^[5]
