Festuca thurberi is a species of grass known by the common name Thurber's fescue.

It is native to a section of the western United States encompassing New Mexico, Utah, Colorado, and Wyoming.

[1] This perennial grass forms a large, dense tuft of stout stems which may just exceed one meter in maximum height.

In the Rocky Mountains it often begins its growth under the snowpack, producing chlorotic leaves until it encounters sunlight.

Cattle grazing in quaking aspen communities consume this grass in large quantities.
