Chlamydopodium is a genus of green algae in the family Characiochloridaceae.

[1] Chlamydopodium consists of solitary or clustered cells attached to a substrate via a pad of mucilage.

Cells contain a single parietal chloroplast which is band-shaped and may be variously lobed; there are one to five pyrenoids covered in a starch sheath.

[1] Chlamydopodium reproduces asexually via biflagellate zoospores, which contain a band-shaped chloroplast, a stigma, and two contractile vacuoles.

It is similar to the genus Characiochloris, and differs by lacking contractile vacuoles in its vegetative cells.
