Abbeystead House is a large country house to the east of the village of Abbeystead, Lancashire, England, some 12 km south-east of Lancaster. It is recorded in the National Heritage List for England as a designated Grade II listed building.

John Douglas was an English architect who designed over 500 buildings in Cheshire, North Wales, and northwest England, in particular in the estate of Eaton Hall. He was trained in Lancaster and practised throughout his career from an office in Chester. Initially he ran the practice on his own, but from 1884 until two years before his death he worked in partnerships with two of his former assistants.
