Erigeron sionis is a North American species of flowering plant in the daisy family known by the common name Zion fleabane. It has been found in the southwestern United States, only in southern Utah. Some of the populations are inside Zion National Park, after which the species is named.

It is a perennial, colony-forming herb up to 25 cm (10 inches) tall, spreading by means of stolons running along the surface of the ground. The inflorescence generally contains 1-4 flower heads. Each head contains 22–46 white ray florets surrounding many yellow disc florets.
