Dennis Spooner (1 December 1932 – 20 September 1986) was an English television writer and script editor, known primarily for his programmes about fictional spies and his work in children's television in the 1960s. He had long-lasting professional working relationships with a number of other British screenwriters and producers, notably Brian Clemens, Terry Nation, Monty Berman and Richard Harris, with whom he developed several programmes. Though he was a contributor to BBC programmes, his work made him one of the most prolific writers of televised output from ITC Entertainment.
