Christopher Miles Boardman, (born 26 August 1968) is a British former racing cyclist. A time trial and prologue specialist, Boardman won the inaugural men's World time trial championship in 1994, won the individual pursuit gold medal at the 1992 Summer Olympics, broke the world hour record three times, and won three prologue stages (and consequently wore the yellow jersey on three occasions) at the Tour de France.

Boardman's nickname is "The Professor", for his meticulous attention to detail in preparation and training, and his technical know-how. He had an altitude tent built in his house to help him prepare for the hour record attempt, although in an interview he claimed that all it did was help him focus. Boardman focused on interval training. He was a keen user of power measuring devices. For his winning ways in time trials and prologues of stage races, he was also nicknamed "Mr. Prologue".

Boardman is also notable for having used the Lotus 108 time trial bicycle designed by Mike Burrows and built by the sports car manufacturer Lotus. Later he worked with the UK carbon fibre bike specialist Hotta, to produce other time-trial frame designs, which he raced in various events including world championships, and Olympic games. He is now involved in producing commercial and competition bikes with the Boardman Bikes and Boardman Elite ventures.

In 1992, he was awarded an MBE for services to cycling.
