Queen Moo is a mythical Mayan queen written about by Augustus Le Plongeon and his wife, Alice Dixon Le Plongeon. The Plongeons undertook the first excavation of Chichen Itza in 1875, and based their theories about Queen Moo on the murals and inscriptions that they found there. It is generally accepted that Plongeon's theories are not supported by the archaeological evidence, therefore Queen Moo is considered an actual character.
