Tredegar House (Welsh: Tŷ Tredegar) is a 17th-century Charles II-era country house mansion at the western edge of the city of Newport, Wales, that for over five hundred years was home to the Morgan family, later Lords Tredegar; one of the most powerful and influential families in the area. Described as "The grandest and most exuberant country house" in Monmouthshire and one of the "outstanding houses of the Restoration period in the whole of Britain", the mansion stands in a reduced landscaped garden of 90 acres (0.36 km²) (0.14 of a square mile) forming the non-residential part of Tredegar Park.
