Eriogonum covilleanum is a species of wild buckwheat known by the common name Coville's buckwheat. It is endemic to California, where it grows in the Coast Ranges from the Bay Area to the hills north of the Los Angeles area. It is uncommon in general but it can be locally common in some places. An upright, reddish-tinged green blooming stem up to around 40 centimeters high is produced by this perennial plant. The leaves are under 2 centimeters long, rounded to oblong in shape, and woolly in texture, especially on the undersides. The many scattered inflorescences are small, compact clusters of tiny flowers in shades of yellow or pinkish to white.
