Star Trek Fanfiction
Gene Roddenberry's starfaring universe is where media fanfiction as we know it began — Kirk/Spock zines in the 1960s coined the term 'slash.' Today the AO3 umbrella spans the Original Series and its films, the Kelvin reboot's enormous K/S boom, Picard-era Next Generation fic, Deep Space Nine's Garak/Bashir literary tradition, and new-series fandoms for Discovery and Strange New Worlds. Across every era the throughlines hold: five-year-mission episodic adventure, alien cultural negotiation, and devotion between officers written with half a century of craft behind it.

by annataylor

Popular Star Trek Ships
Spirk
James T. Kirk/Spock
The captain and his first officer are the original slash ship — 'slash' literally comes from the Kirk/Spock zines of the 1970s. Gene Roddenberry himself coined 't'hy'la' for their bond, and every Trek era since has added fuel, from the Motion Picture to the Kelvin films.
16,000 works →
McKirk
Leonard McCoy/James T. Kirk
Bones met Jim Kirk on a shuttle while threatening to throw up on him, and the Kelvin timeline turned their friendship into the heart of the reboot. The grumpy doctor patching up his reckless captain is a dynamic fandom found impossible to leave platonic.
6,000 works →
Garashir
Elim Garak/Julian Bashir
Deep Space Nine's exiled Cardassian spy invited the young doctor to lunch in episode three and spent seven seasons lying to him charmingly. Andrew Robinson played Garak as openly flirtatious — his own words — making this Trek's most text-adjacent slash ship.
6,000 works →
Spuhura
Spock/Nyota Uhura
The Kelvin films made Spock and Uhura an established couple from the first movie — a quiet, adult relationship between a grieving Vulcan and the linguist who refuses to let him retreat into logic. Strange New Worlds added an earlier, wistful chapter to their story.
2,500 works →
Qcard
Q/Jean-Luc Picard
An omnipotent trickster who could torment any being in the universe spends decades returning to one starship captain, and Star Trek: Picard finally let Q call it what it was: attachment. The trial of humanity doubles as the longest courtship in the quadrant.
2,500 works →
Spones
Spock/Leonard McCoy
The Enterprise's Vulcan and its irascible doctor have bickered about logic versus feeling since 1966, a sparring match fandom reads as decades of devotion in disguise. McCoy carrying Spock's living soul in his head canonically sealed the bond.
2,000 works →
McSpirk
James T. Kirk/Spock/Leonard McCoy
Star Trek's command trio — heart, logic, and the captain who needs both — anchors one of fandom's oldest OT3s, with roots in the original zine era. McSpirk resolves the franchise's foundational triangle by keeping all three on the bridge and in love.
