Harcourt Powell (1718–1782) was a British politician who sat in the House of Commons between 1754 and 1775.
Powell was the son of Thomas Powell of the Six Clerks office, and his wife Anne Harcourt, daughter of Sir Philip Harcourt.
[1] The Powell family came from Pembrokeshire and held the manor of Uggaton near Brighstone.
In 1768 he had to fight a contested election at Newtown, standing jointly with Sir John Barrington against Sir Thomas Worsley and John Glynn.
He was returned unopposed again in 1774, but on 21 March 1775 he accepted 4,000 guineas to vacate his seat in Parliament and convey his three burgages at Newtown to Sir Richard Worsley.
