Hazelwood House is an 18th-century Palladian style country house located in a 70-acre (28 ha) demesne in the parish of Calry, approximately 2 miles (3 km) south-east of the town of Sligo in north-west Ireland. The building's entry in the National Inventory of Architectural Heritage database describes it as one of County Sligo's "most neglected treasures", and of architectural, social and historical value. It is listed on the Record of Protected Structures for the Sligo County Council administrative area. Hazelwood, an ancient area of woodland, forms part of the original estate.
