The Golden Root or The Golden Trunk is a literary fairy tale written by Giambattista Basile in the Pentamerone, as the fourth story of the fifth day. It is considered to be one of two rewritings of the Graeco-Roman myth of "Cupid and Psyche" by Basile, the other being "Lo Catenaccio".

The Pentamerone, subtitled Lo cunto de li cunti, is a seventeenth-century Neapolitan fairy tale collection by Italian poet and courtier Giambattista Basile.
