In Greek mythology, Peneus (; ) was a Thessalian river god, one of the three thousand Rivers (Potamoi), a child of Oceanus and Tethys. The nymph Creusa bore him one son, Hypseus, who was King of the Lapiths, and three daughters, Menippe (mother of Phrastor by Pelasgus), Daphne and Stilbe. He also had a son Atrax with Bura, and Andreus with an unknown consort. Tricce, eponym of the city Tricca, was mentioned as his daughter. Some sources state that he was the father of Cyrene, alternately known as his granddaughter through Hypseus. Daphne, in an Arcadian version of the myth, was, instead, the daughter of the river god Ladon.
