[ 2 syll. e-rin, er-in ] The baby girl name Erin is also used as a boy name, though it is far more popular for girls. It is pronounced EH-RihN or EH-R-ahN †. Erin is of Celtic origin. It is used mainly in English and Irish. The meaning of Erin is 'Irish woman'. It is derived from the word Éire with the meaning 'Ireland'. The name is Anglicized from Eireann, which is from Éire, the traditional Gaelic name for Ireland. The name Erin itself has been used as a poetic name for Ireland in many poems and songs, and it thus evokes a sentimental appeal among people of Irish roots. The given name was first used by English speakers in the 19th century. It initially appeared in the USA, and then it spread to Canada, Australia, and England via Irish migrants. It has been increasingly adopted by people with no Irish associations.
