Eriophyllum lanatum, with the common names common woolly sunflower and Oregon sunshine, is a common, widespread, North American plant in the sunflower family.

The Lewis and Clark Expedition reportedly saw this plant growing above their camp on the Clearwater River (near present-day Kamiah, Idaho), and collected two specimens of the then scientifically unnamed plant on 6 June 1806. Botanist Frederick Traugott Pursh studied the plants collected on the Lewis and Clark Expedition, after their return to the east. His first classification and naming of the species, as Actinella lanata, was published in his 1813 book A Systematic Arrangement and Description of The Plants of North America.

The name "woolly sunflower" is often used to describe any member of the genus Eriophyllum.

Eriophyllum lanatum is native to western North America, commonly growing in many dry, open places below 10,000 feet (3,000 m) in elevation. It prefers full sun and well-drained soil, but it also grows on rocky slopes and bluffs.

It is most common across California, in chaparral, oak woodland, mixed evergreen forest, and yellow pine forest and other conifer forests, grassland, and sagebrush scrub habitats.

It also grows north through Oregon into British Columbia and east through Idaho into Wyoming, and through Nevada into Utah. Its range reaches south into Mexico in Baja California state.
