Arthur Orton (20 March 1834 – 1 April 1898) was an English man who has generally been identified by legal historians and commentators as the "Tichborne Claimant", who in two celebrated court cases both fascinated and shocked Victorian society in the 1860s and 1870s. Commentators have generally concurred with the court's verdict that the Claimant was Orton, but some 20th-century analysts have raised uncertainties about this accepted view, and have suggested that, although the Orton identity remains the most likely, a lingering doubt persists.
