Archey's frog, Leiopelma archeyi, is an archaic, rare frog native to New Zealand, one of only three (or four) extant species belonging to the taxonomic family Leiopelmatidae. It is named after Sir Gilbert Archey, the former Director of the Auckland Institute. The holotype is held at the Auckland War Memorial Museum. It is found only in the Coromandel Peninsula and near Te Kuiti in the North Island of New Zealand. This species, along with others in the family, have changed little over the past 200 million years, and thus represent "living fossils".
