Townley Hall is a Georgian country house which stands in parkland at Tullyallen some 5 km west of Drogheda, County Louth in the Republic of Ireland.

The house is 27 metres (89 feet) square, built in local stone with simple neoclassical lines, broken only by a Doric portico.

[citation needed][2] Mrs Townley Balfour, wife of the grandson of Blayney jnr, died childless in 1955 and the property passed to her cousin David Crichton.

In 1967 Professor Frank Mitchell of Trinity College bought the house with some 25 hectares (62 acres) of surrounding land and ran it as a study centre for several years.

The house is now owned by the School of Philosophy and Economic Science, a registered charity based in Ballsbridge Dublin, who use it as a residential study centre.
