Let’s be honest. When you think about Michael Crichton’s 1990 novel or the 1993 Steven Spielberg masterpiece, you probably think of a summer blockbuster. You see the lunchboxes. You hear John Williams’ soaring, triumphant orchestral theme that makes you feel like you’re flying over a prehistoric island. But then, you remember the kitchen scene. You remember the vibrating water glass. You remember the lawyer getting snatched off a toilet. Suddenly, figuring out what genre is Jurassic Park gets a whole lot more complicated than just labeling it a "kids' movie with lizards."
It’s a hybrid. It always has been.
At its core, Jurassic Park is a science fiction thriller, but it masquerades as a traditional adventure film. This tonal tightrope is exactly why the movie hasn't aged a day since 1993. It’s not just one thing. Depending on which scene you’re watching, it shifts from a philosophical debate about bioethics to a "creature feature" that would make 1950s B-movie directors weep with envy.
The Science Fiction Foundation
Most people get it wrong. They think the dinosaurs are the point. They aren't.
The dinosaurs are the consequence.
If you look at the DNA—pun intended—of the story, Jurassic Park belongs to the "Hard Science Fiction" genre. Michael Crichton wasn't just some guy writing about monsters; he was obsessed with chaos theory, fractal geometry, and the burgeoning field of biotechnology. In the early 90s, the idea of extracting ancient DNA from amber was actually being discussed in serious scientific circles, like the work of George Poinar Jr. Crichton took that real-world curiosity and turned it into a cautionary tale.
Science fiction usually asks a "What If?" question. Jurassic Park asks: "What if we treated the most powerful technology in human history like a theme park attraction?"
It’s about the hubris of man. It’s Frankenstein with a bigger budget and better visual effects. When Ian Malcolm, played with chaotic energy by Jeff Goldblum, gives his famous "life finds a way" speech, he’s not talking about dinosaurs. He’s talking about the inherent instability of complex systems. That is pure, unadulterated sci-fi.
Why it Feels Like a Horror Movie
Is it a horror movie? Well, ask any eight-year-old who watched it in a theater in 1993.

The answer is a terrified "Yes."
Spielberg is a master of suspense, and he leaned heavily into the Techno-Horror subgenre here. Think about the Dilophosaurus scene with Dennis Nedry. That isn't an adventure sequence. It’s a slasher beat. You have a character trapped in a confined space—a stalled Jeep—while a predator plays with its food. The use of "jump scares" and the slow buildup of dread are hallmarks of the horror genre.
- The rattling of the fences.
- The rhythmic thump of the T-Rex footsteps.
- The silence before the raptors click their claws on the linoleum floor.
These are tropes taken straight from the slasher handbook. Spielberg famously used "the shark you don't see" technique in Jaws, and he applied that same logic to the first half of Jurassic Park. We don't even see a "scary" dinosaur for the first 45 minutes of the film. We see a sick Triceratops. We see a Brachiosaurus eating leaves. We are lulled into a sense of wonder—the Adventure genre—before the floor drops out and we are plunged into a survival horror scenario.
The "Creature Feature" Tradition
To understand what genre is Jurassic Park, you have to look back at the 1950s. Films like The Beast from 20,000 Fathoms or Godzilla (1954) paved the way. These are "Creature Features."
However, Jurassic Park elevated the genre. Before 1993, monsters were usually guys in rubber suits or stop-motion puppets that looked a bit jerky. Dennis Muren, Stan Winston, and the team at ILM changed the game. They used a mix of groundbreaking CGI and life-sized animatronics to create something that didn't feel like a movie monster. It felt like an animal.
That distinction is huge.
When a movie treats its "monster" like a biological entity with its own instincts and behaviors, it moves into the Natural Horror territory. It's the same category as The Birds or Cujo. The terror comes from the fact that these animals aren't "evil." They’re just hungry. Or they’re protecting their territory. That grounded reality makes the stakes feel much higher than a standard fantasy film.
Action-Adventure and the Spielberg Touch
We can't ignore the spectacle. Jurassic Park is a quintessential Action-Adventure film.

It follows the classic "Hero’s Journey" to an extent, though Alan Grant’s journey is mostly about his refusal to become a father figure, symbolized by his hatred of children. The set pieces—the T-Rex chase, the gallimimus stampede, the final showdown in the rotunda—are designed for maximum adrenaline.
Adventure films usually rely on a sense of "The Great Escape." The characters are placed in an exotic, dangerous location (Isla Nublar) and must use their wits to get out. It’s got the "ticking clock" element common in thrillers. The power is out. The phones are down. The boat is leaving. This pacing is what makes it a "blockbuster." It’s designed to keep your heart rate up, not just through fear, but through excitement.
The Literary Roots: Techno-Thriller
If we're talking specifically about the book, the genre is definitely a Techno-Thriller.
Crichton basically invented this genre. A techno-thriller focuses on technical details—how the computer systems work, the specific sequence of the DNA, the logistics of the park’s security—and uses those details to drive the plot. In the novel, there is a lot more time spent on the "Nedry" subplot and the corporate espionage involving BioSyn.
The movie trims a lot of that "tech-speak" to keep the pace fast, but the DNA of the techno-thriller remains. The entire plot hinges on a computer programmer (Nedry) creating a back-door in the code to steal embryos. That’s not a magic spell or a supernatural curse. It’s a realistic, technical failure.
Misconceptions: It's Not "Fantasy"
A common mistake is labeling Jurassic Park as fantasy. It’s not.
Fantasy involves elements that cannot be explained by science—magic, dragons, or supernatural forces. Jurassic Park goes to great lengths to explain how it happened. Even if the science is flawed (we now know we can't get viable DNA from 65-million-year-old mosquitoes), the story operates within the framework of science.
This is an important distinction because it changes how the audience perceives the threat. In a fantasy movie, you expect the impossible. In Jurassic Park, you expect the logical. If a fence is electric, it stays shut. If the power goes out, the fence is just wires. That logic is what creates the tension.

The Genre Evolution of the Sequels
It’s worth noting that the genre has shifted as the franchise grew.
- The Lost World: Jurassic Park leaned harder into the Action/War vibe.
- Jurassic Park III felt more like a Survival Slosher.
- Jurassic World moved into Meta-Commentary/Corporate Satire.
- Jurassic World: Fallen Kingdom actually split itself in half—the first half was a Disaster Movie, and the second half was a Gothic Horror film set in a mansion.
But the original? The 1993 film is the perfect "Four-Quadrant" movie because it hits so many genres at once. It’s a family drama (Grant learning to like kids), a sci-fi warning, a horror movie, and a grand adventure.
The Final Verdict
So, if someone asks you what genre is Jurassic Park, you can give them the short answer or the smart answer.
The short answer: It’s a Science Fiction Adventure.
The smart answer: It’s a Techno-Horror Thriller that uses the visual language of an epic adventure to deliver a philosophical warning about the dangers of unregulated biological science.
It’s a movie that defies a single box. That’s why we’re still talking about it thirty years later. It’s not just about the dinosaurs; it’s about the feeling of being very small in a world that humans no longer control.
How to Experience the Genre for Yourself
If you want to truly "feel" the genre nuances of the franchise, try these steps:
- Read the Book First: Honestly, the novel is much darker. It’s a cynical techno-thriller where John Hammond is a villain, not a kindly grandfather. It clarifies the "sci-fi" aspect better than the movie.
- Watch the "Kitchen Scene" in Isolation: Turn off the sound. Watch the cinematography. You’ll realize it’s filmed exactly like a horror movie, using shadows and reflections to build terror.
- Compare to "Westworld": Michael Crichton wrote and directed the original Westworld (1973). Watch it. You’ll see that Jurassic Park is basically the same genre: "Amusement Park Goes Wrong due to Human Greed."
- Listen to the Score: Notice how John Williams uses dissonant, scary strings during the raptor hunt versus the melodic horns during the island arrival. The music tells you the genre is shifting in real-time.
Stop looking at it as a "dinosaur movie." Start looking at it as a cautionary tale about what happens when "can do" outpaces "should do." That is where the real meat of the story lies.
Practical Insight: If you're a writer or creator trying to emulate this, the "Secret Sauce" of the Jurassic Park genre is the Contrast. You need the "Wonder" to make the "Terror" work. Without the beautiful Brachiosaurus scene, the T-Rex attack wouldn't be as shocking. You have to earn the horror by showing the beauty first.
