James Tiberius "Jim" Kirk was a male Human Starfleet officer who lived during the 23rd century.

Kirk was arguably one of the most famous and highly decorated starship captains in the history of Starfleet. As the commanding officer of the Constitution-class starships USS Enterprise and USS Enterprise-A, Kirk served United Federation of Planets interests as an explorer, soldier, diplomat, and time traveler.

His missions were known to grade school students and required reading for Starfleet cadets alike. (Star Trek Generations; VOY: "Q2") The Academy's own Early Starfleet History noted such exploits as saving of the Pelosians from extinction, despite it being a violation of the Prime Directive, much like he had with the Baezians and Chenari years earlier, as well as a record-setting number of first contacts. (VOY: "Q2") Kirk's record stood until the 2370s, when Captain Kathryn Janeway set a new record by being the first Federation captain in the previously unexplored Delta Quadrant.
