Fiona does not end up with anyone in particular in Shameless (US); the show leaves her romantic future open and unresolved.

She has several major relationships over the series — especially with Jimmy/Steve, Gus, and Sean — but every one of them collapses before her exit, and the writers never reunite her on-screen with any of them. In her final storyline, she takes a payout from a real estate deal, leaves Chicago to start over on her own, and the series never shows her settling down with a partner afterward.

Fans often have their own “headcanon” that she eventually reunites with Jimmy/Steve or finds someone new off-screen, but that’s fandom speculation, not something the series confirms.

So, if you’re wondering “who does Fiona end up with in Shameless?” the canon answer is: no one. She ends the show single, with a fresh start and her future left to the audience’s imagination.
