''Corallorhiza mertensiana'', or Pacific coralroot, is a coralroot orchid native to the shady conifer forests of northwestern North America. It also goes by the common names Western coralroot and Mertens' coralroot. ''Corallorhiza mertensiana'' was previously considered a subspecies of ''Corallorhiza maculata'' but was given species rank in 1997 by Freudenstein.
