Honestly, it’s kinda impressive how Saoirse Ronan managed to keep her personal life so quiet while being one of the most recognizable faces in Hollywood. You’ve seen her in everything from Lady Bird to Little Women, but for the longest time, her romantic life was basically a giant question mark. That changed when people started noticing her spending a lot of time with a certain Scottish actor.
So, let's get right to it. Who is Saoirse Ronan’s husband? Her husband is Jack Lowden, an acclaimed actor in his own right. If you’ve watched the Apple TV+ hit Slow Horses, you definitely know him as River Cartwright.
They didn't just meet at a glitzy industry party. They actually met on the set of the 2018 film Mary Queen of Scots. In a bit of weird foreshadowing, Lowden played Lord Darnley—the onscreen husband of Ronan’s Mary Stuart. Turns out, the chemistry wasn't just for the cameras.
The secret wedding in Edinburgh
While most celebrities want the biggest, loudest wedding possible, these two went the opposite direction. They tied the knot in July 2024. It wasn't in Los Angeles or a massive Irish estate. Instead, they chose a very low-key civil ceremony at the Edinburgh Central Registrar's Office.
The guest list was tiny. Only a handful of their closest friends and family were there. In fact, guests were reportedly sworn to secrecy. We only really found out about it because of the Scottish civil marriage registry records. They didn't post a single photo. No "just married" Instagram reel. Nothing.
Who exactly is Jack Lowden?
Jack isn't just "Saoirse Ronan's husband." He’s a massive talent. Born in 1990 in Essex but raised in the Scottish Borders village of Oxton, he’s deeply proud of his roots. He even supports Scottish independence.
Before he was winning over TV audiences in Slow Horses, he was a theater powerhouse. He won an Olivier Award back in 2014 for his role in Ghosts. He’s been in huge movies like Christopher Nolan's Dunkirk, where he played a fighter pilot, and he portrayed the poet Siegfried Sassoon in Benediction.
He’s also a producer. He and Saoirse actually worked together again on the 2024 film The Outrun, which he produced through their company, Arcade Pictures. It's cool to see a couple that doesn't just live together but actually creates art together.
A timeline of their relationship
- 2018: They meet on the set of Mary Queen of Scots.
- 2019-2023: They are spotted together at various events like the Australian Open and fashion shows, but they rarely talk about each other in interviews.

- July 2024: They get married in a private ceremony in Edinburgh.

Life away from the cameras
The couple spends most of their time between London—specifically a townhouse in Islington—and the Scottish Borders. They have a dog named Fran.
What’s interesting is how they talk about each other when they actually do talk. Jack once called Saoirse a "force of nature" and "utterly fearless." Saoirse, on the other hand, has mentioned how much she values his opinion above almost anyone else’s.
They seem to bond over the simple stuff. Saoirse recently joked on a podcast that she knew Jack was "the one" because of how much he appreciated her love for food. She recalled a moment she was devouring a burger and realized he just loved that about her. It’s those small, human details that make them feel less like "A-list stars" and more like a normal couple.
What's next for the couple?
Now that they are parents and collaborators, their careers are only getting more intertwined. Jack is reportedly taking on the iconic role of Mr. Darcy in a new Netflix adaptation of Pride & Prejudice, and Saoirse is exploring more work behind the camera.
If you want to keep up with them, don't look at their social media—they barely use it for personal stuff. Your best bet is watching their projects.
