Atriplex pacifica is a species of saltbush known by the common names Davidson's saltbush, South Coast saltbush, and Pacific orach. It is native to the coastline of Southern California, including the Channel Islands, and Baja California, where it grows in saline habitat on the immediate coastline, such as beach bluffs. It is an uncommon plant, chiefly because much of its native habitat has been drastically altered.
