Helen Preece Chipchase Smith (1897 - 1990) was a British equestrian who also rode in America.^[1] She was the only woman briefly entered in the 1912 Summer Olympics.

She was the daughter of Ambrose Preese, of Fulham road, London.^[2] Her mother was considered a "noted horsewoman" in England.^[3] In June 1910, she did well in the Olympia Horse Show.^[4] In the next Olympia Horse Show, in June 1911, she was considered a "favorite" and was personally congratulated by Queen Alexandra afterward.^[5][6] In November 1911, she won the gold cup at the Madison Square National Horse Show in New York City.^[7][8] At the show, she rode the horses, Sapelio, owned by George Chipchase and the winning Sceptre, owned by James Dunn.^[8]

In 1912, while still in school, she attempted to enter the modern pentathlon in the 1912 Summer Olympic Games.^[9] For a short time, she was the only woman slated to compete at the games.^[10][11] She was ultimately not allowed to compete because she was a female.^[9] The response from the Olympic committee to her request to enter was "hostile."^[12]

In 1914, she placed second in Ladies' saddle horse riding and first in Park and road hacks, riding on Sceptre.^[13]

On March 20, 1915, she married George H. Chipchase in New York.^[14] A few months later, his former wife sued Preese in a Massachusetts court for using the Chipchase name and also claiming that there had been no divorce.^[14]

In December 1934, she was married again in Boston to John Leslie Smith, a riding instructor.^[15]
