Gregynog (Welsh pronunciation: [ɡrɛˈɡənɔɡ]) is a large country mansion in the village of Tregynon, 4 miles (6.4 km) northwest of Newtown in the old county of Montgomeryshire, now Powys in mid Wales. There has been a settlement on the site since the twelfth century. From the fifteenth to the nineteenth century it was the home of the Blayney and Hanbury-Tracy families. In 1960 it was transferred to the University of Wales as a conference and study centre by Margaret Davies, granddaughter of the nineteenth century industrial magnate and philanthropist, David Davies 'Top Sawyer' of Llandinam.
The gardens and park surrounding the house are listed at Grade I on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.
