Christophe Guyot (born July 13, 1962) is a French speed and endurance motorcycle rider, 24 Hours of Le Mans winner, Endurance World champion and French Superbike champion. Born in Marseille, he founded the GMT94 motorcycle team.

As of 2017, he was the only rider/manager to win the 24 Hours of Le Mans motorbike race.

Following a third world title in Endurance (2017), and still led by Guyot, GMT94 moved up to world speed in 2018 in the Supersport class (600cc) and became runner-up in the 2019 world championship. GMT94 and Guyot entered the World Superbike Championship (1000cc) in 2023.

Guyot is also a consultant for the Eurosport television channel.

After obtaining a school-teaching diploma in 1984, and then a DEUG in history in 1986, Guyot decided in 1989 at the age of 28 to leave teaching school to concentrate on motorcycling. For his first season, in the Promosport 350 and behind the handlebars of a Yamaha RD 350 LC, he won two races and finished on the rostrum three times. In 1990, he moved to the upper class and rode in Promosport 750, a category in which he won three victories.

In 1991, Guyot decided to found his own team, Guyot Motorcycle Team, called GMT94, 94 being the French department number of Val-de-Marne. He raced for three seasons in the Superbike World Championship, accumulating a total of 16 races throughout the 1991, 1992 and 1993 seasons.

GMT94 was the official Yamaha team in the EWC (Endurance World Championship) until 2018, and is currently the official Yamaha team in the Supersport World Championship. The team won 3 endurance world championship titles, 3 victories in the 24 Hours Motos and 2 victories in the Bol d'Or, and is also a four-time French Superbike champion. Guyot was also the representative of the riders from 1994 to 2004.

After three years of travelling the world, Guyot decided to return to France winning the title of French Superbike champion in 1998. In 1999, he decided to devote himself exclusively to the Endurance World Championship.
