The Critérium des As was a cycle race that was generally held at the end of the season, with entry by invitation only, for the leading riders of the season. Competitors rode behind pacers on tandems or motorcycles. It was held from 1921 until 1990, mostly in Paris, France but also in Switzerland and Holland. The last Critérium des As was held in 1990 and was replaced by the Roue d'Or des As the following year.
