Anthony Fenn Kemp (1773 – 28 October 1868) was a soldier, merchant and a deputy judge advocate of the colony of New South Wales (the predecessor to the Australian State). He was one of the key participants in the "Rum Rebellion" that removed William Bligh, the appointed governor of the colony, and established an interim military government. He was later permitted to settle in Van Diemen's Land and became a successful merchant and farmer there.
Kemp was born in England, near Aldgate, London, probably around 1773. He was educated in Greenwich, London. After finishing school, he travelled to the United States and to France. On his return, he purchased a commission as an ensign in the New South Wales Corps, a regiment raised in England specifically to maintain discipline in the colony of New South Wales. It later was to become known as the Rum Corps, because of the monopoly by its officers on the supply of the liquor in the early years of the colony.
Fenn typically appears as a surname. Occasionally it appears as a middle name, pen name or name of a fictional character.
