Clonmel is the county town and largest settlement of County Tipperary, Ireland. The town is noted in Irish history for its resistance to the Cromwellian army which sacked the towns of Drogheda and Wexford. With the exception of the townland of Suir Island, most of the borough is situated in the civil parish of "St Mary's" which is part of the ancient barony of Iffa and Offa East.
