Search for Martha Plimpton husband and you’ll find a lot of people asking the same question. It's one of those Hollywood mysteries that isn't really a mystery once you look at the facts.
Honestly? Martha Plimpton doesn't have a husband. She has never been married.
If you were expecting a secret wedding or a messy divorce story, you're gonna be disappointed. But the reason people keep searching for it is actually pretty fascinating. It’s tied to a massive legacy of 80s nostalgia and one of the most tragic romances in film history.
The River Phoenix Connection
Most of the confusion starts here. When people think of Martha Plimpton’s personal life, they immediately think of River Phoenix. They were the "it" couple of the late 1980s.

They met on the set of The Mosquito Coast when they were just teenagers. Martha was 15; River was 15. At first, they didn't even like each other. River famously said they "couldn't stand each other" during their first meeting. But then, things changed. They grew up a bit, filmed Running on Empty together, and became inseparable.
They were together for about four years. In Hollywood time, that’s basically a lifetime. Because they were so iconic—think shaved heads at the Oscars and shared activism—many fans just assumed they would eventually tie the knot.
Why they didn't last
It wasn't a lack of love. Martha has been incredibly open about this recently. In 2025, she sat down on Jesse Tyler Ferguson’s podcast, Dinner’s on Me, and got really real about it. She called River her "first love" and admitted she misses him every single day.
But there was a dark side. River was struggling with substance abuse. Martha has admitted that toward the end of their relationship, she was "screaming, fighting, and begging" for him to change. She eventually realized she couldn't save him. They broke up in 1989, though they stayed close friends until his death in 1993.
That One Engagement You Might Have Forgotten
While the River Phoenix era is the most famous, it wasn't Martha's only serious relationship. In the mid-90s, she was actually engaged.
The guy was Jon Patrick Walker, an actor known for his work on Broadway and in various TV roles. They were a fixture of the New York theater scene for a while. They never actually made it down the aisle, though. They split up before the wedding happened, and Jon eventually went on to marry actress Hope Davis.
Since then? Martha has kept things pretty quiet.
She isn't hiding a secret spouse. She just seems to value her independence. She’s moved to London, built a massive career on the West End, and continues to be one of the most respected character actresses in the business.

Why We Are So Obsessed With Her Marital Status
There is this weird thing we do with child stars. We want them to have the "happily ever after" that fits a script. Martha was in The Goonies. She was in Parenthood. She was half of a legendary power couple.
When a celebrity chooses to live a full, successful life without a traditional marriage, the internet assumes there’s a missing piece of the puzzle. There isn't.
What she's doing now
- Living in London: She moved there several years ago and seems to love the change of pace.
- Stage Work: She’s been nominated for multiple Tonys and has found a second home in theater.
- Activism: Just like she was in the 80s, she’s still a fierce advocate for reproductive rights.
The Reality of Martha Plimpton's Personal Life
If you’re looking for a Martha Plimpton husband, you’re looking for someone who doesn’t exist. She’s 55, she’s thriving, and she’s proof that a "complete" life doesn't require a marriage certificate.
Kinda refreshing, right?
In a world where every celebrity relationship is a PR stunt or a TikTok drama, Martha just... lives. She protects her peace. She talks about River when she wants to honor his memory, but she doesn't let her past define her present.

Just remember that the real story is about a woman who chose her own path, regardless of the Hollywood "wife" narrative.
