Red-legged frog is a common name for two species of frog of the west coast of North America. The red-legged frog requires stream side, woodland environments for survival. The red-legged frog is further subdivided into two categories:

These two have long been thought mere subspecies of Rana aurora, R. a. draytonii and R. a. aurora, respectively, with "red-legged frog" accordingly applying to that species as a whole. Analysis of mtDNA cytochrome b sequence data points to there being two distinct species, however.[1]
