Frances Elizabeth Willis (May 20, 1899, Metropolis IL – July 23, 1983, Redlands CA)[1] was an American diplomat who served as the U.S. ambassador to Switzerland, Norway and Sri Lanka.

Willis held posts starting in Chile in 1928, then Sweden, Belgium and Spain during WW II, the U.S. State Department, England, Finland, Switzerland, Norway and Sri Lanka.

[10] Her appointment caused some unease to the thoroughly conservative Swiss government, which struggled to find a proper form of address for a "Fräulein" ambassador.

[11] Even more diplomatic headaches were caused by Willis' frank anti-Communist rhetoric, which enraged the Swiss left-wing press.

[5][12] After her retirement she was appointed U.S. delegate to the 20th United Nations General Assembly's Third Commission Human Rights and Social Development, working with Arthur Goldberg.

[12] She was also appointed chairman (as she insisted on calling her title) of the University of Redlands Johnston College Board of Overseers and Long Range Planning Committee.
