The Federation Secretary of the Exterior is a senior member of the Federation President's cabinet and the head of the Federation Department of the Exterior, responsible for helping to coordinate foreign policy and affairs. (ST novel: Articles of the Federation)

In the 23rd century, the Secretary of the Exterior's title was Federation Secretary of State, in accordance with the Department of the Exterior's former name. (TNG novel: The Genesis Wave, Book 1)

The Secretary of the Exterior seems to roughly correspond to the role of the United States Secretary of State or a Foreign Minister. The Genesis Wave: Book I contains reference to the Federation foreign minister in 2286 being called the "Secretary of State;" it is conjectured that the Federation Departments of State and the Exterior are the same ministry, simply renamed. Alternately, the full formal title may be or have been something akin to "Secretary of State for the Exterior," just as Canada's foreign minister was once known as Secretary of State for External Affairs.
