Helenium bigelovii is a North American perennial plant in the sunflower family, commonly known as Bigelow's sneezeweed.

It is found at moderate and higher elevations (3000–10,000 ft) in the foothills and mountains of California and Oregon: Cascades, Coast Ranges, Klamath Mountains, Sierra Nevada, etc.

Helenium bigelovii is a perennial herb sometimes as much as 130 cm (51 in; 4.5 ft) tall.

Each head has 14-20 yellow ray florets (bending backwards and with teeth at the tips) surrounding sometimes as many as 800 disc florets (yellow at first, turning brown as they get older).
