Corallorhiza trifida, commonly known as early coralroot, northern coralroot, or yellow coralroot, is a coralroot orchid native to North America and Eurasia, with a circumboreal distribution. The species has been reported from the United States, Canada, Russia, China, Japan, Korea, India, Nepal, Kashmir, Greenland, Pakistan, and almost every country in Europe.

Corallorhiza trifida is yellowish green in color, leafless, and partially myco-heterotrophic, deriving some, but not all of its nutrients from association with fungi of genus Tomentella. It also contains chlorophyll, with which it supplies some of its own carbon nutrition via autotrophy.
