Wyethia mollis is a species of flowering plant in the family Asteraceae known by the common name woolly mule's ears.

The plant is hairy to woolly in texture, sometimes losing its hairs with age.

It grows in forests and other mountain habitat such as dry open meadows with sagebrush.

It grows from a tough taproot and caudex unit, producing a stem 30 to 40 centimeters tall, and reaching a meter in height at times.
