Feihyla hansenae, also known as Hansen's Asian treefrog, Hansen's bushfrog, and Chon Buri pigmy tree frog, is a species of frog in the family Rhacophoridae. As its range is currently known, it is endemic to Thailand, although it is likely that its true range extends into Myanmar, Cambodia, and Laos. The nominal species consists of two lineages that may represent distinct species. The specific name hansenae honours Dora Hansen, friend of Doris Mable Cochran who described this species.
