Alexandre François Étienne Jean Bouin (; 21 December 1888 – 29 September 1914) was a French middle-distance runner. He competed in the 1500m at the 1908 Olympics and the 5000m at the 1912 Olympics. He won a silver medal in the 5000m in 1912, behind Hannes Kolehmainen. His race against Kolehmainen has long been regarded as one of the most memorable moments in running. Kolehmainen and Bouin quickly pulled away from the others, with Bouin leading and Kolehmainen repeatedly trying to pass him. Kolehmainen succeeded only 20 metres from the finish, winning by 0.1 seconds. Both contenders broke the world record.
