Claude Criquielion (11 January 1957 – 18 February 2015) was a Belgian professional road bicycle racer who raced between 1979 and 1990. In 1984, Criquielion became the world road race champion in Barcelona, Spain on a gruelling course. He had five top-ten finishes in the Tour de France. At the national championship race in 1985, he tested positive for Pervitin, but received no repercussions. The head of the laboratory at Ghent University, which had administered the analysis, subsequently resigned his post in the Medical Commission of the Belgian Cycling Association (KBWB) in protest.
