Pedicularis groenlandica is a showy flowering plant in the family Orobanchaceae which is known by the common names elephant's head and elephanthead lousewort. This erect plant can grow to a height of 80 centimetres (31 in). Its sharply-toothed fernlike leaves are located low on the stout stem. The stem is topped with a large inflorescence of bright pink to purple or white flowers. Each flower has a long, pointed beak which curves upward, superficially resembling the trunk of an elephant, and the lateral lobes of the flower resemble an elephant's ears. Like other louseworts and related broomrape genera, this is a root parasite which obtains nutrients from the roots of other plants by piercing them with haustoria. This plant is found in the high mountain ranges of western North America, particularly the Cascades and High Sierra, much of Canada and Greenland. It grows in wet environments such as riverbanks.

The inflorescence is a raceme of flowers occupying the top of the stem. Each flower is a centimeter long or slightly longer, white to yellowish in color, and divided into a coiled or curved beak-like upper lip and a flat, three-lobed lower lip. The fruit is a capsule up to a centimeter long containing seeds with netted surfaces.
