Harry Fragson (2 July 1869 – 31 December 1913), born Léon Philippe Pot, was a British music hall singer and comedian, born in Soho, London. Having scored a number of successful performances in England, Fragson moved to Paris, where he developed an act imitating French music hall performers. The act was popular, and allowed him to introduce his own material. He returned to London in 1905 and became a popular in pantomime.
He is perhaps best known for his song "Hello, Hello, Who's Your Lady Friend?" which he recorded shortly before his untimely death in 1913 (he was murdered by his father).
