Colostethus inguinalis is a species of frog in the family Dendrobatidae. It is endemic to northwestern and northcentral Colombia. Its vernacular name is common rocket frog, although this name can also refer to Colostethus panamansis that until 2004 was considered a junior synonym of Colostethus inguinalis. Much of the older literature on Colostethus inguinalis is actually about Colostethus panamansis.
