Michael David Fisher (born 12 December 1950 in Acton) is a fictional character in the BBC sitcom Only Fools and Horses. He was publican of the Nag's Head, the fictional Peckham pub that frequently serves as a setting in the show. Mike was portrayed by Kenneth MacDonald, and appeared in the show from 1983 to 1996. In the 2015 book He Who Dares, a fictional Del Boy autobiography, it is said that Mike's prison sentence had been reduced and he had retired to the Isle of Wight to write a memoir of his time inside. Del had left him a number of messages, but had never received any responses.
