Viscount of Frendraught
Viscount of Frendraught was a title in the Peerage of Scotland.

It was created on 29 August 1642, along with the title Lord Crichton, for James Crichton, younger of Frendraught, son of James Crichton of Frendraught, who thereafter became known as Crichton of Kinnairdie. The Crichtons of Frendraught were heirs-male of William Crichton, 1st Lord Crichton, who was Lord Chancellor under James II and whose title had been forfeit in 1484.
