Most great horror movies have some kind of boogeyman to terrorize the protagonist. These murderous monsters tend to be unstoppable forces lurking in the shadows, waiting for the opportune moment. Other times, they’re inside the protagonist, causing all sorts of chaos and evil. Whatever their modus operandi, the most frightening horror movie villains find ways to make the audience squirm, squeal, or otherwise scream in horror at their disfigured bodies or wicked deeds. So lock the doors and close the blinds, here are the25 Most Terrifying Horror Movie Villains.

Xenomorphs
With sharp teeth, a twisted and dark exoskeleton, acid for blood, and a sneaky presence, these monsters in the Alien franchise are still pretty frightening. Especially when they burst out of your chest after eating spaghetti.
Cujo
Dogs are supposed to be man’s best friend, but this furry monster from Castle Rock, Maine, is anything but. It didn’t take much to fear this rabies-infected hound with its blood soaked coat and jagged teeth. After the movie was over, we never looked at dogs the same way again.
Samara Morgan
From the creepy way she’s stands in the woods with her long hair over her face to, you know, her climbing out of the television set to murder you, it’s safe to say Samara is pretty darn scary.
Sam
While he acts as more of an ominous presence in Trick r’ Treat, it’s hard to deny his devious and eerie nature, lurking in the shadows, ensuring the horrors of Halloween are honored.
The Pale Man
Also known as “The Thing That Slumbers There,” this monster from Pan’s Labyrinth is both creepy and haunting with its penchant for eating small children and for having its eyes in the palms of its hands.
Mister Babadook
This dark, tall, and intimidating presence of a man with a top hat was scary enough before Amelia faced him, stripping him of his form and showing us a dark mass of teeth and claws.
The Thing (1982)
This titular beast lurking in the frozen tundra is at first a shape-shifting creature before it reveals its true, horrendous form. Hats off to John Carpenter’s team for creating one ugly, horrifying monster.
Brundlefly
When Seth Brundle creates a teleportation device and decides to teleport himself, everything goes wrong when a fly enters the device with him, fusing their DNA together and creating Brundlefly. The combination of Goldblum’s acting, the disgusting makeup, and the tragedy of his transformation creates a horrific story of science gone wrong.
Captain Spaulding
All you have to do is take one look at this monster’s ghastly yellow grin on his bearded clown face to know he’s not going to make you a balloon animal. There’s no question this murderous clown is horrifying.
Damien Thorn
As we all know, this little child isn’t any ordinary child. He’s the Son of Satan and the Antichrist, causing all sorts of malevolent and murderous things around him.
Pinhead
This main villain of the Hellraiser series is also called The Hell Priest and is a Cenobite from the Order of the Gash. But all you really need to do is take one look at his pale, nail covered face to know he’s a living nightmare.
Charles Lee Ray
Also known as the Lakeshore Strangler, this serial killer dies but finds a way to send his spirit into a Good Guy doll. As the doll, he wickedly terrorizes the unfortunate family that originally thinks he’s just a harmless toy.
John Doe
This serial killer punishes and kills his victims who have committed the seven deadly sins, wanting to wake up an apathetic world. His cold, mathematical, and ruthless personality gave us the chills especially at the very end.
Leatherface
This chainsaw wielding maniac wears a mask made of human skin, hence his name, and slaughters people in brutal ways. What makes his character even more terrifying is that it’s based on a real serial killer – Ed Gein.
Norman Bates
This serial killer and owner of the Bates Motel in California mostly looked like a normal guy, but his awkward and creepy demeanor slowly showed itself as the movie Psycho unfolded. He was also based on Ed Gein.
Hannibal Lecter
Also known as “Hannibal the Cannibal,” this serial killer’s character was notoriously brought to life by Anthony Hopkins. While he is behind bars most of the time in Silence of the Lambs, all it really took was the evil look in his eye and his ominous voice to scare us under a blanket.
Jigsaw
The uniqueness of this villain is his approach. While most villains terrorize their victims personally, Jigsaw masterminds terrifying traps and games, often forcing them to make horrible choices.
Annie Wilkes
We only need one word to describe why this villain is so terrifying: hobbling. Of course, Kathy Bates sells this obsessive fan’s devilish personality, causing every author to hope they never run into a fan like her.
Freddy Krueger
Wielding sharp claws and capable of invading your nightmares, this scarred and striped menace was once a serial killer who became a Dream Demon. Once he kills you in the dream world, you die in the real world and he absorbs your soul.
Pennywise
This evil creature from Stephen King’s macroverse can take any shape, but he regularly shows up as a clown to lure people into the dark. He prefers children over adults and believes frightened flesh tastes better. Whether portrayed by Tim Curry or Alex Skarsgard, this sewer monster is absolutely terrifying.
Jason Voorhees
Villain of the Friday the 13th franchise, this hockey mask and machete wielding monster haunts Camp Crystal Lake and is practically an unstoppable killing machine. As iconic as he is brutal, he’s left a lasting impression on pop culture and cinema for years.
Candyman
This titular character with a hook for a hand is a brutal killer out for revenge. He wears a trench coat to hide his body’s horrific mutilations and hollowed out abdomen infested with bees. On top of that, he’s essentially nigh-unstoppable, making him a terrifying force to be reckoned with.
Jack Torrance
The slow downward spiral into insanity makes this villain somewhat tragic but that doesn’t negate his terrifying nature. It’s this slow descent that makes him so creepy and disturbing. Once he finally breaks, his maniacal, axe-wielding form is still haunting to his day.
Michael Myers
Main baddie of the Halloween franchise, this ominous, steak knife wielding serial killer started his villainy as a child when he murdered his older sister. After breaking out of his insane asylum, he went back to his murderous ways, haunting Laurie Strode. He’s a creepy and omnipresent being, lurking around every corner, waiting to strike.
Regan MacNeil
While she’s technically not the one at fault, but rather the evil demon Pazuzu that possesses her, it’s still hard not to think of her as the villain. And what a villain she is. From her evil appearance to the wicked things she does and says to the priests, it’s easy to see why some believe The Exorcist to be the scariest movie of all time.
