Isocoma humilis, common names Zion goldenbush or Zion jimmyweed, is a rare North American plant species in the family Asteraceae. It has been found only in southern Utah in the United States. Some of the populations lie inside Zion National Park.
Isocoma humilis is a low, branching shrub rarely more than 8 cm (3 in) tall. Herbage is covered with copious hairs. Leaves are narrow, oblong to oblanceolate, up to 50 mm (2.0 in) long, deeply lobed. Each flower head is up to 7 mm (0.28 in) wide (fairly large for the genus) and has 19-28 disc flowers but no ray flowers.
