Erigeron pinnatisectus is a species of flowering plant in the family Asteraceae known by the common name feather-leaf fleabane. It is native to the Rocky Mountains of Wyoming, Colorado, and New Mexico.
Erigeron pinnatisectus is a small perennial herb rarely more than 11 centimeters (4.4 inches) tall, producing a woody taproot. The leaves are covered with wool.

The plant grows on buffs, ledges, and steep slopes at high altitudes, often above tree line.
