Stanley Michael Bailey Hailwood, MBE GM (2 April 1940 – 23 March 1981) was an English professional motorcycle racer and racing driver. He is regarded by many as one of the greatest racers of all time. He competed in the Grand Prix motorcycle world championships from 1958 to 1967 and in Formula One between 1963 and 1974. Hailwood was known as "Mike The Bike" because of his natural riding ability on motorcycles with a range of engine capacities.

A nine-time world champion, Hailwood won 76 Grand Prix races during his motorcycle racing career, including 14 Isle of Man TT victories and four consecutive 500 cc world championships. After his motorcycle racing career concluded, he went on to compete in Formula One and other classes of car racing, becoming one of the few men to compete at Grand Prix level in both motorcycle and car racing. In 1974 he drove a works Yardley-sponsored McLaren M23 and sometimes outpaced team leader Emerson Fittipaldi. He left Formula One after being injured badly at the 1974 German Grand Prix at the Nürburgring and retired to New Zealand, where he was involved with a marine engineering business together with former McLaren manager Phil Kerr. He returned to motorcycle racing at the age of 38, taking victory at the 1978 Isle of Man TT.
