Deschampsia is a genus of plants in the grass family, commonly known as hair grass[6] or tussock grass. The genus is widespread across many countries.[7][8]

The genus is named for French physician and naturalist Louis Auguste Deschamps (1765–1842).[7][9]

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,[10][11] and one of only two flowering plants of Antarctica.[12][13]

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