Helen Crlenkovich (Croatian: Crljenković[1]) (Akron, Ohio, January 14, 1921 - Los Angeles, California, July 19, 1955) was one of the most successful athletes in America and the world on the three-meter springboard and the ten-meter platform.

She declined an offer to turn professional for US$250 (equivalent to $5,440 in 2023) per week in 1940 to dive for Billy Rose's Aquacade at the 1940 Golden Gate International Exposition.

[10] During a World War II retirement "Klinky", as she was affectionately known, swam in the Aqua Follies at the Minneapolis Aquatennial (held July 18–26, 1942),[11] and was married in 1943, becoming Helen Morgan.

Crlenkovich appears twice as a twisting diver above San Francisco Bay in Diego Rivera's 1940 mural Pan American Unity.

[5] Along with Georgia Coleman, Pat McCormick and Micki King, all Hall of Famers, she has been closer to the men's standards of diving excellence than any of the other great women in history.

[5] In September 2008, Helen received posthumous recognition by the World Acrobatic Congress held in Las Vegas for her life achievements in swimming and diving.

[17] Crlenkovich attended San Francisco Junior College with a major in physical education (previously pre-law) while working nights as a hotel accountant and practicing dives for two hours a day.
