Arnica lanceolata is a North American species of arnica in the sunflower family, known by the common name clasping arnica or lanceleaf arnica. It has a disjunct (discontinuous) distribution in western North America and northeastern North America.

Arnica lanceolata is a perennial herb usually growing from a small rhizome and producing one or more hairy, glandular stems. The stems are lined with 5 to 10 pairs of oval-shaped, toothed leaves up to 12 centimeters long. The inflorescence is a cluster of several daisy-like flower heads with a center of brownish disc florets and a fringe of yellow ray florets 1 to 2 centimeters long. The fruit is a cylindrical achene covered in hairs and with a light brown pappus at one end.
