Grindelia is a genus of plants native to the Americas belonging to the family Asteraceae, (Compositae). G. squarrosa, a plant with bright yellow flowers indigenous to much of the United States, is commonly called curlycup gumweed. G. robusta, found in the western states, is a coastal scrub bush that is reputed to have several medicinal uses. Hairy gumweed, Grindelia cuneifolia, occurs in brackish coastal marshes of western North America, such as in some portions of the San Francisco Bay perimeter.

Grindelia species are used as food plants by the larvae of some Lepidoptera species including Schinia mortua.
