Halloween is creeping up, and there's no better way to get in the spirit than with a Scooby-Doo marathon. The franchise has been solving mysteries for decades, from classic Saturday-morning cartoons to direct-to-video movies and live-action reboots. Whether you prefer the old-school costumed villains or the newer supernatural threats, there's a Scooby adventure for every kind of fan.
To help you plan your spooky watchlist, we've ranked the ten best Scooby-Doo mysteries to watch around Halloween. These picks range from feature-length films to standalone episodes, but all of them deliver the perfect mix of chills, laughs, and Scooby Snacks.
10. Scooby-Doo! and the Ghoul School (1988)
In this made-for-TV movie, Shaggy, Scooby, and Scrappy-Doo take jobs as gym teachers at a school for monster girls. The Halloween connection is strong: the students are young ghouls, and a wicked witch wants to control them. It's a weird but charming entry from the late '80s, and it pairs well with other oddities like Scooby-Doo! and the Boo Brothers and Scooby-Doo! and the Reluctant Werewolf. Younger viewers will love the silly scares, even if Mirror Monster Shaggy still gives us nightmares.
9. "The Headless Horseman of Halloween" (The Scooby-Doo Show)
Season 1, Episode 5 of The Scooby-Doo Show pits the gang against a pumpkin-headed rider straight out of "The Legend of Sleepy Hollow." It's a fun, 22-minute romp that also features Scooby-Dum, the short-lived country cousin of Scooby. The mystery is easy to crack, but the Halloween atmosphere and the literary nod make it a seasonal must-watch.
8. "Halloween" (Be Cool, Scooby-Doo!)
Be Cool, Scooby-Doo! may not be everyone's favorite iteration, but its Halloween episode is a standout. Fred takes center stage when a witch from his past resurfaces. The gang heads into the woods to trap Baba Yaga, and the result is a surprisingly heartfelt and funny adventure. The art style is divisive, but the story is worth it.
7. "Ghost Who's Coming to Dinner" (A Pup Named Scooby-Doo)
This episode of A Pup Named Scooby-Doo finds the pint-sized Mystery Inc. hired by a ghost to solve a haunted-house mystery. It's a clever twist on the usual formula, blending real ghosts with costumed crooks. Plus, seeing the gang in Halloween costumes is a treat.
6. Happy Halloween, Scooby-Doo! (2020)
This direct-to-video film is one of the few explicitly Halloween-themed Scooby movies. It features Elvira, Mistress of the Dark (played by Cassandra Peterson), and a soft crossover with DC Comics' Scarecrow. The result is a lighthearted horror-comedy that's perfect for kids and adults who love a good pun.

5. "A Halloween Hassle at Dracula's Castle" (The New Scooby-Doo Mysteries)
In this episode, the gang attends a Halloween party at a spooky castle, only to find themselves face-to-face with Dracula and other monsters. It's a classic Scooby caper with plenty of twists and turns. The gothic setting and festive vibe make it a perennial favorite.
4. Scooby-Doo on Zombie Island (1998)
Often hailed as the best Scooby-Doo movie, Zombie Island took the franchise in a darker, more serious direction. The gang reunites after years apart and travels to a haunted island where the monsters are real. The animation, story, and genuine scares make it a standout. It's a must-watch for any fan, especially around Halloween.
3. Scooby-Doo! and the Witch's Ghost (1999)
This follow-up to Zombie Island sends the gang to a New England town famous for its witch trials. They meet a famous horror writer (based on Stephen King) and uncover a real supernatural threat. The autumn setting and witchy theme make it ideal for October viewing. The Hex Girls, a goth rock band introduced here, became fan favorites.
2. "The Backstage Rage" (Scooby-Doo, Where Are You!)
While not explicitly Halloween-themed, this classic episode features a creepy puppet master and a haunted theater. The atmosphere is pure Halloween, and the mystery is one of the best from the original series. It's a reminder of why Scooby-Doo, Where Are You! remains iconic.
1. "A Night of Fright Is No Delight" (Scooby-Doo, Where Are You!)
This episode has everything: a haunted mansion, a creepy will reading, and the terrifying Phantom Shadows. The gang must spend the night in a spooky house to inherit a fortune, but a ghostly figure has other plans. It's the quintessential Scooby-Doo mystery, and it's perfect for Halloween.
