Wyethia is a genus of North American flowering plants in the family Asteraceae. First published by Thomas Nuttall in J. Acad. Nat. Sci. Philadelphia vol.7 on page 39 in 1834.

These plants are commonly referred to as mule's ears. They are short, low to the ground golden-rayed wildflowers that resemble miniature sunflowers. The genus is named for an early explorer of the western United States, American Nathaniel Jarvis Wyeth, 1802–1856.
