Addison Lee Cresswell (28 June 1960 – 23 December 2013) was a British comedy talent agent and producer. He was notable for finding many stand-up "alternative" comedians at the Edinburgh Festival Fringe and at other venues, promoting them and finding spots for them on television and radio over a 30-year period from the 1980s. He has been called "one of the most influential people in British comedy", "arguably the most powerful man in UK comedy" for two decades and "the Darth Vader of the Fringe".
