A station chief is a government official who is the head of a team, post or function usually in a foreign country. Historically it commonly referred to the head of a defensible structure such as an ambassador's residence or colonial outpost. In Germany a Stationsleiter (station leader) was the government's chief representative in a colonial possession such as the South Sea Islands. It may also be used to refer to the manager of remote scientific stations such as those in the Antarctic and Jarvis Island, an uninhabited minor U.S. Pacific island possession.
The Station Chief, also called Chief of Station, is the top U.S. Central Intelligence Agency official stationed in a foreign country who manages all CIA operations in that country, equivalent to a KGB Resident. The station chief is often a senior U.S. intelligence officer who represents the Office of the Director of National Intelligence (ODNI) in his or her respective foreign government, whose true name is known to the host nation and other intelligence agencies.  Former officers are not usually allowed to include their position as a station chief in their résumé even after their covers have been lifted.
