Sukio Hirashito was a female Human politician in the 23rd century.

In 2269, she served as President of the Federation General Council, and that year presided over the Council session addressed by Spock regarding the question of Talin IV's status as a de facto Federation Member State. (TOS novel: Prime Directive)

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.
