George Sutton Titheradge (9 December 1848 – 22 January 1916) was an English-Australian actor.
Titheradge was born at Portsea, Portsmouth, England, eldest son of George Robert Titheradge (an accountant) and Sarah Isabelle Emblim. He made his first appearance on the stage at the Theatre Royal, Portsmouth, subsequently supported Charles Dillon in Shakespearian plays, and in 1873 played the junior lead at Bristol. In 1876 he was Joseph Surface in the Chippendale classical company, and in the same year played Hamlet at Calcutta. On 1 January 1877 he was the Herald at the Calcutta Durbar and proclaimed Queen Victoria Empress of India. He made his first appearance in London on 6 October 1877, and on 8 April 1878 played Iago to the Othello of Henry Forrester.
Titheradge visited India a second time and, going on to Melbourne, made his first appearance there in May 1879 as Lord Arthur Chilton in False Shame; F. H. Pollock also making his Australian debut. He joined the London Comedy Company at Sydney in 1880. After a world tour including the United States, Titheradge was engaged in 1883 by J. C. Williamson and Garner to come to Australia and play Wilfred Denver in The Silver King. He made a great success in this character, and in leading parts in other popular dramas of the period. He joined the Brough and Boucicault company in 1887, and for ten years played lead in plays by Robertson, Grundy, Jones, Pinero and other dramatists of the period. There was one Shakespearian production, Much Ado About Nothing, in which Titheradge was an excellent Benedick to the Beatrice of Mrs Brough.
