The village lies within a townland that has a similar name. The village's name is usually spelt Ballerin, while the townland's name is usually spelt Boleran. Earlier spellings of these names include Ballyerin (1654) and Ballyirin (1613). All are believed to come from Irish Baile Uí Shírín 'Ó Shírín's townland/settlement'.[1][2] However, the local Gaelic Athletic Association club uses the Irish name Baile Iarainn,[3] meaning "townland/settlement of iron".
