Hippolyte Aucouturier (17 October 1876 in La Celle, Allier, France – 22 April 1944 in Paris, France) was a French professional road bicycle racer. Aucouturier, a professional between 1900 and 1908, won two stages at the first Tour de France in 1903 and won three stages and finished second in the 1905 Tour de France. He also won Paris–Roubaix twice, in 1903 and 1904. His elder brother Francois was also a racing cyclist.
Aucouturier was an outspoken man whom the Tour organiser, Henri Desgrange, referred to in L'Auto as Le Terrible.
