Fairfax House is a Georgian townhouse located at No. 27, Castlegate, York, England, near Clifford's Tower and York Castle Museum. It was probably built in the early 1740s for a local merchant and in 1759 it was purchased by Charles Gregory Fairfax, 9th Viscount Fairfax of Emley, who arranged for the interior to be remodelled by John Carr . After the Viscount's death in 1772, the house was sold and subsequently passed through a number of local families before spending some time as a Gentleman's Club, a Building Society and a cinema. The property was bought by York Civic Trust in the 1980s and completely restored to its former grandeur. Fairfax House is now a museum open to the public and a Grade I listed building.
