Nancy Churchill Sawin (June 21, 1917 – April 18, 2008) was an American artist, local historian, educator, and field hockey player in Delaware.

She was the daughter of Sanford Wales Sawin, a civil engineer, and Ellen Quigley Sawin, one of the first women in Delaware to earn a master's degree and the daughter of suffragist leader Ada Gould Quigley.

[1][2] In 1938, she began working for the Sanford School, teaching and coaching a number of sports, including field hockey, tennis, softball, basketball, riding, and lacrosse, and serving as head of the school from 1961 to 1974.

Sawin was one of the first group of inductees into the USA Field Hockey Hall of Fame in 1988.

Shortly before retirement, she travelled to Europe and had her first art show "on a clothesline outside a small condo on the Mediterranean."
