Ballyscullion House refers to two country houses built for the Hervey family near Bellaghy in County Londonderry, Northern Ireland, close to Lough Beg at north-west corner of Lough Neagh.

The first Ballyscullion House, sometimes called "Bishop's Folly", was a large house intended for Frederick Hervey, 4th Earl of Bristol and Bishop of Derry. Construction began in 1787 but it was not completed when he died in Italy in 1803. His heir decided to live at his other Irish house, Downhill House, also in County Londonderry, and the partially built Ballyscullion House was demolished by 1825.

A second and much smaller Ballyscullion House was built in 1840 for Admiral Sir Henry William Bruce, and is now owned by the Mulholland family. A military camp was built on the estate in the Second World War by the 202nd Engineering Combat Battalion and occupied by the US 82nd Airborne Division before D-Day.
