The Federation Council President was the official who presided over a given session of the Federation General Council. In 2245, this was Samuel Solomon Qasr. During the session held in 2269, Sukio Hirashito held the position of Federation Council President. (TOS novel: Prime Directive, ST reference: Federation: The First 150 Years)

Prime Directive describes Hirashito as both "this session's Council President," and as "President of the Federation." However, her role as Federation President during this period is contradicted by several sources, including Last Unicorn Games' Star Trek: The Original Series Core Game Book, and the novels Articles of the Federation and the Errand of Fury trilogy.
