Nanorana ercepeae (common names: torrent paa frog, R.C.P.'s paa frog) is a species of frog in the family Dicroglossidae. It is endemic to western Nepal. Its type locality is Torrent Jiuli Gad (type locality) in Bajhang district (previously Far-Western Nepal and now Sudurpaschim Province). This relatively rare frog is found in stream habitats in upland temperate rainforests. One specimen of P. ercepeae was recorded from the still-water habitats of Rara Lake in Rara National Park. It is threatened by habitat loss and degradation caused by small-scale agricultural development and wood extraction.
