Deschampsia is a genus of plants in the grass family Poaceae,[4] commonly known as hair grass[5] or tussock grass. The genus is widespread across many countries.[6][7]

The genus is named for French physician and naturalist Louis Auguste Deschamps (1765–1842).[6][8]

Deschampsia species are used as food plants by the larvae of some species of Lepidoptera, 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. Deschampsia antarctica is the world's most southern monocot,[9][10] and one of only two flowering plants of Antarctica.[11][12]

Some species, such as D. cespitosa, are grown as ornamental garden plants.
