Blepharidachne kingii is a species of grass known by the common name King's eyelashgrass. It is native to the Great Basin in the United States, where it grows in habitat such as pinyon-juniper woodland. It is rare in California and Idaho, but it is one of the most common grasses of the northeastern deserts of Nevada.
