In Irish mythology Eber Finn (Heber, Eibhear) was a son of Míl Espáine who participated in the Milesian conquest of Ireland.

Once conquered the island was divided between Eber and his brother Eremon, Eber taking the southern half and Eremon the north. Eber was unhappy with this division, feeling that his half was inferior, and went to war against his brother, but was defeated and killed.

His sons were Ir (Irish mythology), Orba, Fearon, and Ferga.
