Deschampsia is a genus of grasses in the family Poaceae, commonly known as hair grass[3] or tussock grass. There are 30 to 40 species.

Deschampsia species are used as food plants by the larvae of some Lepidoptera species including Antler Moth, The Clay, Clouded-bordered Brindle, Common Wainscot, Dark Arches, Dusky Brocade, Shoulder-striped Wainscot, Smoky Wainscot and Wall.

Deschampsia sometimes grow in boggy acidic formations, an example of which is the Portlethen Moss, Scotland. D. antarctica is the world's most southern monocot, and one of only two flowering plants of Antarctica.
