Chanteur was a French Thoroughbred racehorse and sire who was one of a group of French horses, including Caracalla, Marsyas, Arbar and Souverain, which dominated long-distance racing in Europe in the immediate post-war years. Unraced as a two-year-old, Chanteur won the Prix Hocquart in 1945 and the Prix Jean Prat in 1946. He reached his peak as a five-year-old when he won six races including the Prix des Sablons in France and the Coronation Cup in Britain. He was also placed in many important races including the Grand Prix de Paris, Prix de l'Arc de Triomphe, Prix Royal Oak, Prix du Cadran and Ascot Gold Cup. At the end of his racing career he was retired to stand as a breeding stallion in Britain, where he had considerable success as a sire of winners.
