In Greek mythology, Eumolpus (also Eumolpos) was the son of Poseidon and Chione. According to the Bibliotheca, Chione, daughter of Boreas and Oreithyia, pregnant with Eumolpus by Poseidon, was frightened of her father's reaction so she threw the baby into the ocean. Poseidon looked after him and brought him to shore in Ethiopia, where Benthesikyme, a daughter of Poseidon and Amphitrite, raised the child, who then married one of Benthesikyme's two daughters by her Ethiopian husband. Eumolpus however loved a different daughter and was banished because of this. He went with his son Ismarus (or Immaradus) to Thrace. There, he was discovered in a plot to overthrow King Tegyrios and fled to Eleusis.
