Vulpia is a widespread genus of plants in the grass family, native to many countries around the world and naturalized in many of the nations to which it is not native. It is most common in temperate regions.

Vulpia is a part of a group of species known as fescues; Vulpia is sometimes considered a subset of the main fescue genus, Festuca. Many of these fescues are considered noxious weeds in many places.Vulpia myuros is a notable weed.

The genus is named for Johann Samuel Vulpius (1760-1846), a German botanist.

Numerous species once considered part of Vulpia but now regarded as better suited to other genera: Anthosachne Australopyrum Avellinia Festuca Micropyrum Vulpiella
