Buck does not have a confirmed “endgame” partner yet in 9-1-1’s current storyline; as of Season 8, he is single after breaking up with Tommy, and the show is clearly still keeping his romantic future open, including heavy teasing of a possible Buck/Eddie direction that hasn’t been made canon as a couple.

Who does Buck end up with in 9-1-1?

Right now, the honest answer is: there is no official, final “who Buck ends up with” yet. The series is still airing new seasons, and Buck’s love life is very much a work in progress.

The show has instead given him a series of big, emotionally important relationships, and then used Season 7 and 8 to blow that wide open with his bisexuality arc and the Tommy storyline.

Buck’s major relationships so far

Here’s a quick tour of the key people fans usually ask about when they say “who does Buck end up with in 9-1-1?”

  • Abby Clark
    • Buck’s first big, formative relationship in early seasons.
* They bond over calls while she’s a 911 operator, start dating, and she later leaves to travel.

* Buck eventually breaks up with her via letter when it’s clear the long‑distance thing isn’t working.

* In Season 3, she returns engaged to someone else; they get closure, and Buck explicitly frames this as the most transformative relationship of his life, but not his future.
  • Ali Martin
    • They meet after a major earthquake rescue and briefly date.
* Ali ultimately ends things because Buck’s dangerous job is too much for her to handle.
  • Taylor Kelly
    • Reporter Taylor and Buck flirt on and off, hook up, then evolve into a proper couple by Season 5.
* Buck cheats by kissing Lucy Donato, then panics and asks Taylor to move in instead of confessing.

* Later, Taylor lies about how she’ll cover the Jonah serial‑killer story, and Buck breaks up with her in the Season 5 finale.
  • Lucy Donato
    • Fellow firefighter who shares Buck’s reckless streak.
* They share a bar kiss while Buck is still with Taylor; after that, their romantic arc doesn’t really develop.
  • Tommy (Season 7–8)
    • Buck comes out as bisexual in Season 7, and Tommy is his first on‑screen male love interest.
* They flirt, have a rocky first date, but are confirmed to be dating by Maddie and Chimney’s wedding.

* Buck even asks Tommy to move in, but Tommy gently says no, sensing he isn’t Buck’s “soulmate” and that Buck is still figuring out his sexuality.

* In Season 8 Episode 6, Buck finds out Tommy was engaged to Abby for two years and never told him; Buck ends the relationship, trying to protect himself.

* Cast interviews have stressed that this relationship was never meant to be the long‑term answer for Buck.

So none of these partners is presented as “final” or “endgame” so far.

What about Buck and Eddie?

If you’ve seen the internet lately, you know this is the ship.

  • Buck and Eddie’s partnership as firefighters and co‑parents to Christopher has been central to the show for years, with intense emotional intimacy and a lot of “this sure feels like more than friends” energy.
  • Buck’s bisexuality storyline in Season 7, plus his jealousy over Eddie spending time with Tommy, pushes their dynamic into much more obviously romantic subtext.
  • After Buck and Tommy break up in Season 8, the narrative very clearly leaves the door open for Buck and Eddie to explore what might be there.
  • Oliver Stark (Buck’s actor) has publicly said he’s open to Buck/Eddie becoming canon and acknowledges the chemistry between them.

However, as of the latest episodes, they are not an official couple. The show is teasing the possibility, not confirming it as “who Buck ends up with.”

Current status: Where things stand now

Putting it all together:

  • Buck has broken up with Tommy after learning about Tommy’s hidden engagement to Abby.
  • He is single , still working through his sexuality and what he actually wants from a long‑term partner.
  • The show seems intentionally non‑committal about an “endgame” so far, leaving room for future seasons to decide whether that’s Tommy again, someone new, or the long‑teased Buck/Eddie path.
  • There is no confirmed canon answer yet to “who Buck ends up with in 9-1-1” — only strong hints and fan‑favourite possibilities.

So if you’re watching and wondering who Buck’s final partner is meant to be, the truthful, up‑to‑date answer is: the story hasn’t locked that in yet, and the writers are very clearly keeping their options (and our speculation) open.

TL;DR:
Buck does not definitively “end up with” anyone yet in 9-1-1. He’s currently single post‑Tommy, and while the show is strongly hinting at deeper possibilities with Eddie, there’s no canon endgame partner confirmed so far.
