Eleanor Suzanne Daniel (born June 11, 1950), is an American former competition swimmer, four-time Olympic medalist, and former world record-holder.

In her earlier years, Daniel trained with Hall of Fame Coach Mary Freeman Kelly at the Vesper Boat Club team in Philadelphia.

[1] Later, when her family moved to California around 1967, she swam with Hall of Fame Coach Sherm Chavoor's at Arden Hills Swim Club in Sacramento.

[2] Afterward, she switched to the butterfly stroke, which came naturally to her because she was double-jointed in her back and her strength was in her shoulders, and won seven national championships.

[3] She received a gold medal by swimming the butterfly leg for the winning U.S. team in the women's 4×100-meter medley relay, together with teammates Kaye Hall (backstroke), Catie Ball (breaststroke), and Sue Pedersen (freestyle).
