Guy Martin (born 4 November 1981) is a British lorry-mechanic better known publicly as a motorcycle racer turned television presenter of engineering-based projects. Martin started racing in 1998, debuting on road circuits at the Isle of Man TT events in 2004, where he gained 17 podium finishes. He has broken his back twice in racing accidents, in the 2010 TT and the 2015 Ulster Grand Prix.

On 26 July 2017, it was officially announced that Guy Martin had retired from motorcycle racing. In an exclusive interview with the Motorcycle News Martin said: "Racing's been good to me, but I'm bored of it. You spend the early part of the year preparing for the season – testing, racing, talking about it, and then doing it all over again. It's like Groundhog Day. It's time to stop".

Martin starred in "Closer to the Edge", a 2011 documentary on TT racing. He has since presented programmes on various engineering topics and the Channel 4 series "Speed with Guy Martin" when he set speed records in a variety of human and engine powered vehicles.
