Henry Martyn (16 July 1877 – 8 August 1928) was an English cricketer who made 97 first-class appearances for Oxford University and Somerset between 1899 and 1908.
He is described in his Wisden obituary as "one of the finest wicket-keepers ever seen in first-class cricket".
In his 1981 article, John Arlott selected Martyn as the best English wicket-keeper never to play for England.
