You know that kid. The one with the Member's Only jacket, the Prince poster on the wall, and a tongue that moves faster than a pirate ship in a waterslide. Most people just call him Mouth. Honestly, it's one of the most iconic nicknames in cinema history. But if you’re trying to remember the Goonies Mouth real name, it's Clark Devereaux.
Simple, right? Not really.
For a movie that basically defined a generation’s idea of adventure, it's funny how many fans actually forget the real names of the kids. We know Chunk, Data, and Mouth. But Clark? That barely ever comes up. If you watch the movie closely, Mrs. Walsh—Mikey’s mom—is one of the few people who actually uses it. She shouts "Clark!" when he’s being a brat, which is basically his default setting.
The Mystery Behind Clark "Mouth" Devereaux
Mouth is the "lieutenant" of the group. He’s the translator, the joker, and the guy who almost gets his tongue sliced off by Mama Fratelli. But there is a reason his nickname stuck way harder than his actual name. In the 1985 script written by Chris Columbus (based on a story by Steven Spielberg), the character was designed to be the "fast talker."
The Goonies Mouth real name, Clark Devereaux, sounds a bit too sophisticated for a kid who stuffs his pockets with stolen jewels and tricks a housekeeper into thinking there are "marijuana cigarettes" in the attic. The name "Clark" feels buttoned-up. "Mouth" feels like 1980s Astoria, Oregon.

Why we barely hear "Clark"
In the world of The Goonies, nicknames are a survival mechanism. They represent the bond between the kids.
- Mikey is Michael Walsh.
- Chunk is Lawrence Cohen.
- Data is Richard Wang.
- Mouth is Clark Devereaux.
If you go back and watch the opening scenes, the name Clark is used as a tool for authority. When the adults want him to listen, they use his real name. When the kids are being Goonies, it's Mouth. It’s a subtle bit of character writing that makes the world feel lived-in. You probably have friends from middle school whose real names you can’t remember either.
The Actor Behind the Mouth: Corey Feldman
You can’t talk about Mouth without talking about Corey Feldman. In 1985, Feldman was the king of the "snarky kid" archetype. He brought a specific energy to Clark Devereaux that wasn't just scripted; it was lived.
Feldman has mentioned in various interviews over the years—and in his memoir Coreyography—that the set of The Goonies was chaotic in the best way. Director Richard Donner actually let the kids ad-lib a lot. That scene where Mouth is "translating" for Rosalita? That’s pure, distilled Mouth. He’s mean, he’s funny, and he’s clearly the smartest kid in the room who doesn’t know how to shut up.
The Spanish Connection
One of the most impressive things about Mouth (and the reason the Goonies actually survived) was his fluency in Spanish. Without Clark Devereaux, they never would have been able to read One-Eyed Willy’s map. While the translation was played for laughs with Rosalita, it was the key to the entire plot.
Why the Character Still Resonates in 2026
We are officially past the 40th anniversary of the film's release. It’s wild. Even now, fans are obsessed with the Goonies Mouth real name and the trivia surrounding the cast. Maybe it's because Mouth represents that specific brand of childhood confidence. He’s the kid who hides his insecurities behind a wall of jokes.
We see this even more in his "will-they-won't-they" dynamic with Stef (played by Martha Plimpton). It’s classic 80s: he’s annoying to her because he likes her, and she sees right through his "Clark" persona into the goofy kid underneath.
The Goonies Never Say Die
There has been talk for decades about a Goonies 2. In recent years, with the massive success of Ke Huy Quan (Data) winning an Oscar for Everything Everywhere All At Once, the rumors have hit a fever pitch. If a sequel ever happens, seeing an adult Clark Devereaux would be fascinating. Would he still be a smart-mouth? Or did he grow into that sophisticated name?

Common Misconceptions About Mouth
Sometimes people get the characters mixed up. No, Mouth isn't the one with the inventions (that's Data). He’s also not the one who does the Truffle Shuffle (that’s Chunk).
Another weird thing? Some early merchandise and tie-in books actually spelled his last name differently or omitted it entirely. However, the official credits and the "Goon Docks" lore have solidified Clark Devereaux as the canon answer.
If you’re looking for Mouth’s dad in the movie, look for the guy working on the plumbing or the tires during the montage—his dad is played by Nick McLean, who was actually the film’s camera operator! It’s one of those "blink and you'll miss it" cameos that makes the production feel like a giant family affair.
Deep Dive into the Name "Devereaux"
The surname Devereaux is actually of French origin. It’s a bit of an "Easter egg" in the character’s backstory. It suggests a certain level of heritage that contrasts sharply with Mouth’s crude humor and street-smart attitude.
- Origins: The name originally comes from the town of Évreux in Normandy.
- Meaning: It basically translates to "from the river."
- Contrast: Giving a kid with a "trashy" nickname a prestigious French surname was likely a conscious choice by the writers to add depth.
How to Win Your Next Trivia Night
If someone asks you for the Goonies Mouth real name, don't just say Clark. Give them the full Clark Devereaux.
To really show off your expertise, mention that his nickname "Mouth" is explicitly mentioned in the script as being earned because he "never stops talking for a second." It isn't just a random label; it’s his defining personality trait.
Also, keep an eye on the 40th-anniversary docuseries that Corey Feldman has been involved with. It’s focused on the refurbishment of the original Goonies house in Astoria. It’s a great way to see how much the role of Clark still means to him after all these years.
To dig deeper into the world of the Goon Docks, your best bet is to re-watch the film with the "Cast Commentary" track enabled. It features the grown-up actors—Sean Astin, Corey Feldman, Jeff Cohen, and the rest—reminiscing about their time on set. You'll hear them call each other by their real names and their character names interchangeably, which just proves that once you're a Goonie, you're always a Goonie.
