Marquess of Exeter is a title that has been created twice, once in the peerage of England and once in the peerage of the United Kingdom. The first creation came in the peerage of England in 1525 for Henry Courtenay, 2nd Earl of Devon. For more information on this creation, which was forfeited in 1538, see Earl of Devon.
