Lucile Atcherson Curtis (1894–1986) was the first woman in what became the U.S. Foreign Service. Specifically, she was the first woman appointed as a United States Diplomatic Officer or Consular Officer, in 1923; the U.S. would not establish the unified Foreign Service until 1924, at which time Diplomatic and Consular Officers became Foreign Service Officers.

The United States Foreign Service is the primary personnel system used by the diplomatic service of the United States federal government, under the aegis of the United States Department of State. It consists of over 13,000 professionals carrying out the foreign policy of the United States and aiding U.S. citizens abroad. Its current director general is Marcia Bernicat.
