In Greek mythology, Elasippus (Ancient Greek: Ἐλάσιππον means 'horse-riding, knightly') may refer to two personages:

• Elasippus, one of the ten sons of Poseidon and Cleito in Plato's myth of Atlantis.^[1] He was the elder brother of Mestor and his other siblings were Atlas and Eumelus, Ampheres and Evaemon, Mneseus and Autochthon, and lastly, Azaes and Diaprepes.^[2] Elasippus, along with his nine siblings, became the heads of ten royal houses, each ruling a tenth portion of the island, according to a partition made by Poseidon himself, but all subject to the supreme dynasty of Atlas who was the eldest of the ten.^[3]
• Elasippus, son of Haemon and an Achaean soldier who participated in the Trojan War. He was slain by the Amazon queen, Penthesilia.^[4]
