Eurycyda

In Greek mythology, Eurycyda (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 and possibly Naxos.

With Poseidon, she mothered Eleius, after whom the region of Elis was named, as was its people, the Eleans. Several authors refer to her as "Eurypyle".
