Dorothy Poynton-Hill (née Poynton, later Teuber; July 17, 1915 – May 18, 1995) was an American diver who competed at the 1928, 1932 and 1936 Summer Olympics. She won the 10 m platform event in 1932 and 1936, while in the 3 m springboard she took a silver in 1928 and a bronze in 1936. In 1928, at age 13 she became the youngest Olympian to win a medal and, in 1936, the first Olympic diver to win the 10 m platform twice.
After retiring from competitions, Poynton-Hill ran an aquatic club in Los Angeles and appeared in several TV commercials. In 1968, she was inducted into the International Swimming Hall of Fame.
