Meaning & origin
Erin entered U.S. baby name records in 1888, a year that marks the earliest known use tracked by the Social Security Administration. The name reached its peak in 1983, when it ranked highest in popularity, and has been slowly declining since 1985, showing a falling trajectory. In 2025, its rank of 833 and 1-in-4,915 frequency reflect its continued but diminished use. The name has been particularly favored in states like Connecticut, Arkansas, and Louisiana. Despite the decline, Erin remains a recognizable and enduring choice, rooted in Irish heritage.
Erin is an anglicized form of Éireann, the Irish Gaelic genitive of Éire (Ireland). It has been used as a given name since the 19th century, particularly in English-speaking countries. The name is also sometimes associated with the poetic personification of Ireland.
