If you’ve ever watched a guy in a judge’s robe or a Starfleet captain’s uniform snap his fingers and teleport an entire starship across the galaxy just to be annoying, you know Q. He’s the ultimate cosmic prankster. But when people ask who plays Q in Star Trek, the answer usually starts and ends with one name: John de Lancie.
Honestly, it’s hard to imagine anyone else in the role. He has this specific way of being incredibly arrogant while still making you kind of like him. It’s a delicate balance. If you play it too mean, the audience hates you. If you play it too goofy, there’s no threat. De Lancie nailed it from the very first episode of The Next Generation in 1987.
The Man Who Defined the Continuum
John de Lancie didn’t even want to go to the audition at first. He was busy with a play and basically told his agent he didn't have time for some "space show." Talk about a sliding doors moment. When he finally showed up on his lunch break, he walked in, did his thing, and Gene Roddenberry—the creator of Star Trek—told him, "You make my words sound better than they are."
That’s a huge compliment coming from the guy who built the universe.
De Lancie played Q across multiple series, which is pretty rare for a guest star. You've seen him in:

- Star Trek: Lower Decks (The animated version)
- Star Trek: Picard (The emotional "final" goodbye... sort of)
Is it just John de Lancie?
While de Lancie is the Q, the show establishes that "Q" is actually the name of an entire race of beings called the Q Continuum. This means other actors have technically played "a" Q.
For instance, in the Voyager episode "Death Wish," Gerrit Graham played a Q who wanted to end his own life. He was brilliant—much more somber and philosophical than de Lancie’s version. Then there was Corbin Bernsen, who showed up as a "Q2" to strip our Q of his powers.
And we can’t forget the family. In the episode "Q2," John de Lancie’s actual real-life son, Keegan de Lancie, played Q’s son. It added a layer of genuine father-son frustration that you just can't fake. Suzie Plakson also played a female Q, bringing a sharp, regal energy to the Continuum that made even de Lancie’s Q look like a misbehaving toddler.
Why the Casting Mattered for Star Trek: Picard
When Star Trek: Picard Season 2 was announced, the biggest question was how they’d handle an immortal being looking... well, older. John de Lancie is a human, after all. Time happens.

They handled it perfectly. Q shows up, sees Picard has aged, and basically says, "Oh, you want to do it this way? Fine." He snaps his fingers, and suddenly he looks older too. It was a meta-nod to the fans, but it also grounded the character.
The performance in Picard was different. It wasn't just about the jokes. It was about a lonely god facing his own end and trying to make sure his favorite human—Jean-Luc—was going to be okay. It’s probably some of the best acting in the entire franchise.
The Future of Q (and Jack Crusher)
If you stayed through the credits of the Star Trek: Picard series finale, you saw the shocker. Q is back. Even though he "died" in Season 2, he appeared to Jack Crusher (Picard's son).
When Jack points out that Q is supposed to be dead, Q just gives that classic, smug look and says, "I said Jean-Luc's journey was over. Yours is just beginning."

This sets up a massive potential future for the character. Whether we get the rumored Star Trek: Legacy show or not, it’s clear that as long as John de Lancie is willing to put on the cape (or the uniform), he is who plays Q in Star Trek for the foreseeable future.
Surprising Facts About the Performance
- Dyslexia Challenges: De Lancie has been open about having dyslexia, which made the technobabble-heavy scripts of Star Trek a nightmare to memorize. He had to do double the prep work of other actors.
- The Sisko Punch: Avery Brooks (Sisko) actually hit de Lancie pretty hard during their scene in DS9. De Lancie famously quipped, "Picard never hit me!" and Sisko’s response—"I'm not Picard"—is legendary.
- The "I, Q" Book: De Lancie actually co-wrote a novel about the character with Peter David. If you want to see the world through Q’s eyes, that’s the place to go.
What to Watch Next
If you want to see the full evolution of the character, don't just stick to the "best of" lists.
Start with "Encounter at Farpoint" (TNG) to see the god-like judge. Then jump to "Deja Q" (TNG) where he becomes human and gets attacked by a cloud. It’s hilarious. Finish with "Farewell" (Picard Season 2) to see the heart behind the mask.
The best way to appreciate what John de Lancie brought to the table is to watch his chemistry with Patrick Stewart. They are two classically trained stage actors basically doing space Shakespeare. It’s elevated the entire genre.
If you’re looking to dive deeper into the lore, check out the Star Trek novels that focus on the Continuum war. While not strictly television canon, they expand on the "other" Qs and how they interact with the universe when de Lancie isn't around to stir the pot.
Next Steps for Fans:
