Owney and Arra (Irish: Uaithne agus Ara) is a barony in County Tipperary, Ireland.
To the west lies the River Shannon which separates it from County Clare.
Baronies were created after the Norman invasion of Ireland as divisions of counties and were used the administration of justice and the raising of revenue.
In many cases, a barony corresponds to an earlier Gaelic túath which had submitted to the Crown.
However, the neighbouring barony of Kilnamanagh was split into Upper and Lower half-baronies, being allocated to the north and south ridings respectively.
