Huasna, California

Huasna (Chumash: Awasna) is an unincorporated community in southeastern San Luis Obispo County, California, United States.

Huasna is located on the western slope of the southern Santa Lucia Range. Huasna is due east of Arroyo Grande. It is named for Rancho Huasna, granted to Isaac J. Sparks by Governor Manuel Micheltorena in 1843. An adobe ranch house and schoolhouse once stood in the community. The Huasna area was the site of considerable oil exploration in the 1950s, but today the Huasna area is mostly farmland.

The Huasna River runs through the community.
