Newcastle (Irish: An Caisleán Nua) is a barony in County Wicklow, Republic of Ireland.

Newcastle barony derives its name from the village of Newcastle.

Newcastle barony is located in eastern County Wicklow, opening onto the Irish Sea.

The Uí Theig (O'Tighe), cousins to the Uí Máil, are noted early here, as well as the Uí Braen Deilgni, a branch of the Uí Garrchon. This was part of O'Byrne (Ó Broin) country after the 12th century, referred to in Gaelic as Crioch Branach.
