Viscount Powerscourt (// PORZ-kort) 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.
It was created for a third time in 1744 for Richard Wingfield, along with title of Baron Wingfield, of Wingfield in the County of Wexford. He was the grandson of Lewis Wingfield, uncle of the first Viscount of the 1665 creation. Richard Wingfield had earlier represented Boyle in the Irish House of Commons. His eldest son, the second Viscount, represented Stockbridge in the British House of Commons. He was succeeded by his younger brother, the third Viscount, who married into the Noble House of Stratford (from which all latter holders of the Powerscourt Viscountcy descend). The latter's grandson, the fifth Viscount, sat in the House of Lords as an Irish Representative Peer from 1821 to 1823. His son, the sixth Viscount, sat as a Member of Parliament for Bath. On his death the titles passed to his son, the seventh Viscount, who was an Irish Representative Peer from 1865 to 1885. The latter year he was created Baron Powerscourt, of Powerscourt in the County of Wicklow, in the Peerage of the United Kingdom. This peerage gave him and his descendants an automatic seat in the House of Lords until the passing of the House of Lords Act 1999. His son, the eighth Viscount, served as Lord Lieutenant of County Wicklow and was a member of the short-lived Senate of Southern Ireland. As of 2015 the titles are held by his great-grandson, the eleventh Viscount, who succeeded his father in 2015.
