History & Origin

Erin comes from the Irish Gaelic Eirinn, the dative/genitive case of Eire, the Irish name for Ireland. The name Eire derives from the Proto-Celtic goddess name Eriu, one of the three patron goddesses of Ireland in Irish mythology. Using Erin as a given name is thus a deeply patriotic act — naming a child after the land itself.

As a given name, Erin was virtually unknown in the United States before the mid-20th century. It rose steeply in the 1970s and 1980s, particularly among Irish-American families, reaching its peak in the top 20 girls names. It has since moderated but remains a warmly familiar choice. Attorney Erin Brockovich, whose environmental activism was the subject of a 2000 film, gave the name a modern heroic association.

Did you know? The phrase Erin go Bragh — meaning Ireland forever — became one of the most recognized Irish expressions in the world, used at St. Patrick's Day celebrations globally and cementing Erin's association with Irish national pride.
