Laure Manaudou (French pronunciation: ; born 9 October 1986) is a retired French Olympic, world and European champion swimmer. She has held the world record in freestyle events between 200 and 1500 meter. She is the daughter of a French father and a Dutch mother, and she is the older sister of Florent Manaudou who is also an Olympic gold medalist swimmer.
She won the gold medal in the women's 400-meter freestyle at the 2004 Athens Olympics. It was France's first gold medal ever in women's swimming and the first swimming gold medal won by a French athlete since Jean Boiteux's victory in the 400-meter men's freestyle event at Helsinki in 1952. Manaudou won the silver medal in the women's 800-meter freestyle at the Athens Olympics. In that race, she had a quick start but was passed down the stretch by Ai Shibata of Japan. She also won the bronze medal in the women's 100-meter backstroke, thus becoming only the second Frenchwoman to win three medals in a single Olympic Games, Summer or Winter. The first one was the track and field athlete Micheline Ostermeyer in London in 1948. Manaudou was by far the best swimmer on the French team, but she did not have the team support to win a medal in the women's 4×200 m freestyle relay.
