Monotropa uniflora, also known as the Ghost Plant, Indian Pipe, or Corpse Plant is a herbaceous perennial plant, formerly classified in the family Monotropaceae, but now included within the Ericaceae. It is native to temperate regions of Asia, North America and northern South America, but with large gaps between areas. It is generally scarce or rare in occurrence but is common or even ubiquitous in some areas, such as many parts of eastern North America.

The plant is sometimes completely white but commonly has black flecks and a pale pink coloration. Rare variants may have a deep red color.

The stems reach heights of 10–30 cm, clothed with small scale-leaves 5–10 mm long. As its scientific name suggests, and unlike the related Monotropa hypopitys (but like the closely related Monotropastrum humile), the stems bear only a single flower, 10–15 mm long with 3-8 petals. It flowers from early summer to early autumn.
