Actinastrum is a genus of freshwater green algae. It was first described by Gustaf Lagerheim in 1882. Members of the genus are commonly found in eutrophic freshwater ponds and lakes, and have a cosmopolitan distribution.
Traditionally, Actinastrum was placed within the family Coelastraceae based on morphology (spherical, three-dimensional colonies and reproduction by autospores). However, molecular phylogenetic studies have shown that the type species Actinastrum hantzschii is closely related to Chlorella, another autospore-forming genus in the family Chlorellaceae.
