Muskerry East ( ) is one of the
baronies of
Ireland, an historical geographical unit of land. Its chief town is
Ballincollig. It is one of 24 baronies in the county of
Cork. It may also be viewed as a half barony because some time before the 1821 census data, it was divided from its other half -
Muskerry West. Other neighbouring baronies include
Cork to the east (surrounding the city of
Cork),
Duhallow to the north (whose chief town is
Newmarket) and the
Barony of Barretts to the north-east .
