Actinochloridaceae is a family of green algae, in the order Chlamydomonadales.

[1] Actinochloridaceae consists of solitary, spherical cells.

The family is characterized by their chloroplasts, which are typically strongly lobed and dissected, or sometimes broken up into many pieces.

Asexual reproduction occurs when the protoplast of the cell divides into multiple biflagellate zoospores, or less commonly, aplanospores or autospores.
