Castlebaldwin or Bellanagarrigeeny [1] is a townland and small village in County Sligo, Ireland.
The castle outside the village of Castlebaldwin is a fortified 17th-century house rather than a medieval castle, with gun slits in the walls and a machicolation over the door. The walls of the castle are made from stones taken from a nunnery that was near the village. Castlebaldwin is situated near the Carrowkeel Passage Tombs.
