Folliott Wingfield, 1st Viscount Powerscourt (2 November 1642 – c. 5 February 1717), was an Anglo-Irish politician and peer.
William Ponsonby, 1st Viscount Duncannon, was his younger half-brother.
Wingfield served in the Irish House of Commons as the Member of Parliament for County Wicklow between 1661 and 1665.
On 22 February 1665, he was raised to the Peerage of Ireland as Viscount Powerscourt and assumed his seat in the Irish House of Lords.
A descendant of his uncle was created Viscount Powerscourt in 1743 to revive the title.
