What title is given to the head of the Department of State?

The head of the Department of State is designated as the Secretary of State. This title reflects the individual’s role as the principal representative of the United States in foreign affairs and the chief implementer of the country’s diplomatic policies. The Secretary of State is a member of the President’s Cabinet and directly advises the President on international issues, making this position critical in shaping U.S. foreign relations.

The title has historical roots and is a standard practice in the U.S. government, distinguishing it from other countries where a "Foreign Minister" might serve a similar role. The Ambassador serves as a diplomatic envoy in a foreign country but does not lead the Department of State. The term "Director of Foreign Affairs" does not accurately describe the position in the U.S. governmental structure. Hence, the title Secretary of State clearly identifies the head of the Department of State and encapsulates their responsibilities.
