In Greek mythology, Eurycyda[pronunciation?] (Ancient Greek: Εὐρυκύδα, sic) was an Elean princess as the daughter of King Endymion of Elis by either Asterodia, Chromia or Hyperippe. Her brothers were Aetolus, Epeius, Paeon[1] and possibly Naxos.[2]
With Poseidon, she mothered Eleius, after whom the region of Elis was named, as was its people, the Eleans.[3] Several authors refer to her as "Eurypyle".[4]
