In Roman mythology, Canens is a Laurentine nymph or maiden, daughter of Janus and Venilia in some accounts, personification of song and wife of Picus king of Latium. After Circe turns Picus into a woodpecker, Canens searches six or seven days, sings a final song by the Tiber, and wastes away into thin air (or the river). Mother of Faunus in the genealogical strand.

I.Wife of Picus
Ovid's Metamorphoses 14 presents Canens as rare in beauty but rarer in song: her voice moves woods and rocks, tames beasts, and stays rivers. She is married to Picus. While she sings at home, Picus rides out hunting, meets Circe, scorns the witch's love, and is changed into a woodpecker.
Canens searches the Laurentine woods for her husband. On the seventh day grief overcomes her; she melts into thin air beside the Tiber after one last song, and the place is called Canens' grove. Genealogical notes make her mother of Faunus by Picus and, in some handbooks, daughter of Janus and Venilia.
II.Homonym note
Canens is a single Latin figure in Ovid; she is not a Greek catalogue nymph of another name. The atlas node canens is Picus' singing wife of the Circe episode.
