For more than a century, horror films have held a unique power over audiences. They electrify, unsettle, challenge, and thrill — inviting viewers into the darkest corners of imagination and human fear. From the early days of silent cinema to today’s genre-defining masterworks, horror has proven to be one of the most enduring and versatile genres in entertainment.

As thousands of frightening films have stacked up over the decades, a smaller group has emerged as the true titans of terror — movies that not only shaped the genre but changed cinema itself. And while “best-of” lists have always been subjective battlegrounds, IMDb provides one of the most democratic measures of cinematic acclaim. With millions of registered users rating titles on a ten-star scale, IMDb’s aggregate scores represent a broad and global consensus of what audiences continue to value most.

Below is IMDb’s Top 10 Horror Movies of All Time, ranked by their official scores and accompanied by a curated deep dive into the legacy, impact, and terror each film has brought to generations of viewers. Whether you’re a longtime horror fan or a newcomer looking for essential viewing, these are the films that set the gold standard.

10. The Cabinet of Dr. Caligari (1920) — ★ 8.0

More than a century after its release, The Cabinet of Dr. Caligari remains one of the most visually and narratively groundbreaking films ever made. Directed by Robert Wiene, this German Expressionist masterpiece immerses viewers in the jagged, angular, dreamlike world of Hostenwall, a village where reality itself seems warped. Its sets — distorted, painted, surreal — still inspire filmmakers today.

The story follows the mysterious Dr. Caligari, a showman who exhibits a sleepwalker named Cesare, played hauntingly by Conrad Veidt. When a fair attendee turns up dead, suspicion swirls around Caligari’s eerie spectacle. What unfolds is one of cinema’s earliest murder mysteries, though calling it that barely scratches the surface. The film layers psychological horror with commentary on authority, madness, and societal control — themes that resonate as powerfully now as they did in the shadow of World War I.

Multiple remakes have attempted to recapture Caligari’s brilliance, but none have duplicated the film’s boldness or its uncanny atmosphere. It isn’t just a horror film; it’s the foundation on which much of modern cinematic horror was built.

9. What Ever Happened to Baby Jane? (1962) — ★ 8.0

Part psychological horror, part Hollywood Gothic, and part brutal character study, What Ever Happened to Baby Jane? remains one of the most chilling and claustrophobic films ever put to screen. Anchored by powerhouse performances from Joan Crawford and Bette Davis — whose off-screen rivalry is the stuff of legend — the film explores the toxic spiral of sibling resentment.

Crawford’s Blanche and Davis’s Jane Hudson, once child stars, now live together in a decaying Los Angeles mansion. Blanche, confined to a wheelchair, relies on Jane for care, but Jane’s bitterness and unraveling sanity turn their home into a private chamber of cruelty. As Jane’s sadism intensifies, the film examines fame, envy, and aging with a sharpness that still stings.

This is horror stripped of supernatural elements — its chills come from psychological torment and the terrifying fragility of human relationships. Few films have captured descent into madness with such venom and artistry.

8. Rosemary’s Baby (1968) — ★ 8.0

Roman Polanski’s Rosemary’s Baby is one of the most influential horror films ever made, a slow-burn descent into paranoia that masterfully manipulates atmosphere and dread. Mia Farrow’s role as Rosemary Woodhouse, a young woman struggling with a sinister pregnancy, is among the defining performances in horror history.

After moving into the Bramford, a New York apartment building with an unsettling past, Rosemary and her husband (John Cassavetes) become entangled with their overly attentive neighbors. As Rosemary’s pregnancy takes a disturbing turn, she begins to suspect that those around her — possibly even her husband — are plotting something unspeakable.

Anchored by Robert Evans’s iconic production and Polanski’s meticulous direction, the film secured two Oscar nominations, with Ruth Gordon winning for her chillingly polite yet sinister supporting performance. The finale’s reveal remains one of cinema’s most shocking moments, cementing the film as a masterclass in domestic horror and psychological manipulation.

7. Diabolique (1955) — ★ 8.1

Henri-Georges Clouzot’s Diabolique is a film that reshaped the psychological thriller and laid groundwork for the twist-driven horror that would follow decades later. Set in a boarding school run by a cruel headmaster, the film centers on a sinister plot devised by the man’s wife and his mistress — unlikely allies bound by a shared desire for revenge.

Their plan appears foolproof, but what follows is a series of complications, eerie occurrences, and haunting images that build toward one of the most unforgettable climaxes in film history. Even Alfred Hitchcock admitted envy for the film’s mastery of suspense.

Diabolique is not only a landmark in the horror-thriller hybrid; it’s a gold standard. Its influence echoes in films like Psycho, The Sixth Sense, and countless other suspense-driven works.

6. The Exorcist (1973) — ★ 8.1

No horror film has ever replicated the cultural phenomenon that accompanied the release of The Exorcist. Directed by William Friedkin and based on William Peter Blatty’s novel, the movie shocked audiences in 1973 with its visceral depiction of demonic possession — so much so that theaters reported fainting, vomiting, and mass hysteria.

The story of 12-year-old Regan (Linda Blair), who becomes possessed by the demon Pazuzu, is anchored by a fierce emotional core: the desperation of her mother (Ellen Burstyn) and the crisis of faith experienced by the priests (Max von Sydow and Jason Miller) attempting to save her.

The Exorcist earned 10 Oscar nominations, winning two. Its effects remain astonishingly effective, and its themes — faith, innocence, corruption — resonate across generations. Even fifty years later, it is still considered one of the most terrifying films ever made, and arguably the definitive possession movie of all time.

5. Tumbbad (2018) — ★ 8.2

A modern masterpiece from India’s vibrant horror landscape, Tumbbad is one of the most visually striking, thematically rich horror films of the 21st century. Directed by Rahi Anil Barve and Anand Gandhi, the film revolves around a rural family who builds a temple for Hastar — the cursed, never-to-be-worshipped offspring of a goddess.

What begins as a period drama transforms into a harrowing exploration of greed, generational trauma, and mythological terror. Its atmosphere — drenched in monsoon rains, shadows, and dread — creates a cinematic experience unlike anything else on this list.

Tumbbad is a rare gem: a horror film that is equally poetic and petrifying, balancing folklore with philosophical commentary. Its imagery lingers long after the story ends, solidifying its place among the genre’s finest works.

4. The Thing (1982) — ★ 8.2

John Carpenter’s The Thing is a monumental achievement in practical effects, paranoia-driven storytelling, and pure visceral horror. Set in an isolated Antarctic research station, the film follows a group of scientists who encounter a shape-shifting alien capable of perfectly mimicking any life-form.

Kurt Russell leads the ensemble as R.J. MacReady, whose calm under pressure contrasts with the escalating fear tearing the group apart. The creature effects — created by Rob Bottin — remain astonishing today and were groundbreaking upon release. The film’s tension, fueled by distrust and claustrophobia, makes it one of the most suspenseful movies ever crafted.

Though underappreciated upon its debut, The Thing has since become a cornerstone of sci-fi horror and a benchmark for practical effects. Its influence spreads across movies, video games, and modern television.

3. The Shining (1980) — ★ 8.4

Stanley Kubrick’s adaptation of Stephen King’s The Shining is one of the most meticulously crafted horror films ever made. Jack Nicholson’s portrayal of Jack Torrance — a writer succumbing to madness at the remote Overlook Hotel — is nothing short of iconic. Shelley Duvall’s raw, anguished performance as Wendy Torrance remains equally unforgettable.

The film’s terrifying power lies in its precision: Kubrick’s gliding camera movements, unsettling symmetry, and slow, creeping escalation of dread create an atmosphere of pure inevitability. The Overlook itself becomes a character, a maze of haunted memories and psychic echoes.

From the infamous “Here’s Johnny!” moment to the twins in the hallway, The Shining has embedded itself in pop culture and continues to inspire new generations of storytellers. Few films capture the horror of isolation — both physical and psychological — with such artistry.

2. Psycho (1960) — ★ 8.5

There is horror before Psycho, and there is horror after Psycho. Alfred Hitchcock’s chilling masterpiece revolutionized the genre and shattered cinematic conventions. Anthony Perkins delivers a career-defining performance as Norman Bates, the seemingly mild-mannered motel owner with a terrifying secret.

Psycho shocked audiences with its subversive structure, unexpected twists, and the infamous shower scene — still one of the most analyzed sequences in film history. Janet Leigh’s role helped redefine the concept of the “final girl,” while Perkins’s performance remains one of horror’s most nuanced portrayals of madness.

Nominated for four Academy Awards, Psycho is a film whose influence spans more than six decades. It paved the way for the slasher genre, inspired countless filmmakers, and continues to be studied for its daring storytelling and psychological depth.

1. Alien (1979) — ★ 8.5

Ridley Scott’s Alien stands atop IMDb’s horror rankings — and for good reason. Equal parts sci-fi, suspense, and nightmare, the film set a new standard for atmospheric tension and creature design. Sigourney Weaver’s Ellen Ripley remains one of the most iconic heroes in cinematic history, a groundbreaking character whose legacy echoes across decades of genre filmmaking.

The story is brutally simple: a spaceship crew investigates a distress signal and unknowingly brings aboard a deadly extraterrestrial organism. What follows is a slow, agonizing exercise in terror as the alien evolves into one of the most terrifying creatures ever created.

H.R. Giger’s biomechanical design, the claustrophobic setting of the Nostromo, and Scott’s patient direction combine to create a film that feels as fresh today as it did upon release. Winner of the Oscar for Best Visual Effects, Alien launched a franchise and redefined horror in space. Rarely has a film blended suspense, artistry, and primal fear so perfectly.
