Ardee is a barony in County Louth, Ireland. Ity is named after the town of Ardee (Irish: Baile Átha Fhirdhia, "town of Ferdiad's ford").
Ardee is located in central County Louth, between the Keeran River and Dundalk Bay. The barony is bordered to the north by Louth; to the south by Ferrard; and to the west by Lower Slane, County Meath and Farney, County Monaghan.
The barony was formed from the district of Uí Seanchain (Hy Segan, Hy Seanghain, O'Shanaghan). In 841, Vikings established a longphort (raiding base) at Linn Duachaill, Annagassan.
