The Edmund A. Walsh School of Foreign Service (SFS) is the school of international relations at Georgetown University, a congressionally-chartered Jesuit research university in Washington, D.C. Founded in 1919, SFS is the oldest continuously operating school for international affairs in the United States, predating the U.S. Foreign Service by six years. It grants degrees at both undergraduate and graduate levels.

SFS was established by Edmund A. Walsh with the goal of preparing Americans for various international professions in the wake of expanding U.S. involvement in world affairs after World War I. Today, the school hosts a student body of approximately 2,250 from over 100 nations each year. It offers an undergraduate program based in the liberal arts, which leads to the Bachelor of Science in Foreign Service (BSFS) degree, as well as eight interdisciplinary graduate programs.

Based in Washington, D.C., the school also maintains campuses in Doha, Qatar, and Jakarta, Indonesia. SFS is a founding member of the Association of Professional Schools of International Affairs (APSIA), a consortium of the world's leading public policy, public administration, and international affairs schools.
