Mark Watson is a comedian, author and sports pundit. He did his first gig in 2002 and the same year won the Daily Telegraph Open Mic Competition.

Watson has appeared regularly at the Edinburgh Festival Fringe, winning the first ever Panel Prize at the if.comeddies in 2006 and being nominated for Best Newcomer at the 2005 Perrier Comedy Awards. His other awards include the Time Out Critic's Choice Award 2006 and a Barry Award nomination for best show at the Melbourne Comedy Festival 2006.

Watson has performed several unusual shows at the Edinburgh Fringe and Melbourne Festivals, including marathon shows lasting 24 hours and more. The first of these shows was performed at the 2004 Edinburgh Festival Fringe, which lasted 24 hours. At the end of the show he proposed to his girlfriend Emily Howes, who accepted. These shows have also featured guest appearances from other performers such as Tim Key, Tim Minchin, Adam Hills, Daniel Kitson, David O'Doherty, Brendon Burns and John Dorney as the balladeer.

At the 2006 Edinburgh Festival Fringe Watson hosted a literary workshop-cum-interactive comedy show entitled Mark Watson, And His Audience, Write A Novel. The aim was to write, by the end of August, a novel begun from scratch and woven entirely from audience suggestions, with another 2,000 words or so added each day. The novel was not finished within the month.

At the 2007 Fringe, Watson hosted a panel show We Need Answers with Alex Horne and Tim Key. This saw 16 comedians take part in a knock out quiz where all the questions and answers came from text service Any Question Answered. Paul Sinha won the competition, beating Josie Long in the final. We Need Answers returned in 2008 with fewer rounds, Josie Long emerged as winner, beating Sinha in the semi-final and Kristen Schaal in the final.
