William "Willie" D. Davenport (June 8, 1943 – June 17, 2002) was an American sprint runner. He attended Howland High School and college at Southern University and A&M College in Baton Rouge, Louisiana. He competed in the 110 m hurdles at the 1964, 1968, 1972 and 1976 Summer Olympics, winning a gold medal in 1968 and a bronze in 1976, and finishing fourth in 1972. In 1980 he took part in the Winter Olympics as a runner for the American bobsleigh team. Because of the boycott, and the quirk of participating in the Winter Olympics, he was the only U.S. track and field athlete to participate in the 1980 Olympics.
