The House of Stratford is a British aristocratic family, originating in Stratford-on-Avon between the eleventh and thirteenth centuries. The family has produced multiple titles, including Earl of Aldborough, Viscount Amiens, Baron Baltinglass, Viscount Stratford de Redcliffe and the Dugdale Baronets. The Viscount Powerscourt and Baron Wrottesley both claim descent from this House. Historic seats have included Farmcote Manor and Stratford Park in Gloucester, Merevale Hall in Warwickshire, Baltinglass Castle, Belan and Aldborough House in Ireland, and Stratford House in London, amongst many others. The house was at its most powerful in the fourteenth, sixteenth, and eighteenth centuries.

Viscount Powerscourt is a title that has been created three times in the Peerage of Ireland, each time for members of the Wingfield family. It was created first in 1618 for the Chief Governor of Ireland, Richard Wingfield. However, this creation became extinct on his death in 1634. It was created a second time in 1665 for Folliott Wingfield. He was the great-great-grandson of George Wingfield, uncle of the first Viscount of the 1618 creation. However, the 1665 creation also became extinct on the death of its first holder in 1717.
