The best adult cartoon Halloween episodes, show by show.
Twenty Halloween episodes from animated shows made for grown-ups, led by Close Enough and Smiling Friends, with The Venture Bros., Undone and a long South Park run behind them. Not for kids.
Adult cartoon Halloween episodes get to do what family specials can’t: swear, sneer and occasionally go somewhere genuinely dark. This is the after-bedtime list, twenty episodes from animated shows made strictly for grown-ups, so keep the little ones out of the room.
We order the shows by their best-rated episode, using IMDb ratings, and each show’s picks by rating too. That puts Close Enough and Smiling Friends first, with South Park, which fills eight of the twenty spots, in the middle. The span runs from a 1997 South Park to a 2025 Smiling Friends, and where a show tells one continuing story, the note says so.

01
Halloween Enough
The ratings put this one first. It comes from a sitcom about thirty-somethings in Los Angeles that stretches everyday problems into adventures, so pick it when you want a grown-up Halloween episode with some imagination behind it.
-
02
Curse of the Green Halloween Witch
A witch, a curse and a company whose whole job is cheering people up. Smiling Friends swings between sweet and unsettling without warning, so this one suits adults who like Halloween comedy with an edge.
-
03
A Silly Halloween Special
From the show’s first season, the earlier of the two Smiling Friends picks. The title promises silly, but this is a series that likes to let cute things turn creepy, so don’t get too comfortable.
-
04
A Very Venture Halloween
Halloween in a show where the villains already dress up for work. The Venture Bros. spoofs classic adventure cartoons and packs its episodes with references, so it pays off most if you already know the cast.
-
05
Spookyfish
An early South Park from the second season, back when the show was scruffy, crude and still out to shock. It’s the highest-rated South Park here and our pick if you only know the show by reputation.
-
06
Pinkeye
The oldest episode on the list, from South Park’s first season, and the one with the most votes behind it. Rough-edged and unmistakably South Park, it’s for anyone curious what the show’s Halloween looked like when it was brand new.
-
07
A Nightmare on FaceTime
A slasher-movie title crossed with a video-calling app suggests South Park is poking at modern gadgets again. It’s from the show’s middle years and suits anyone who likes crude, topical comedy in a horror costume.
-
08
Hell on Earth 2006
Hell on Earth, with the year stamped on it like an event poster. South Park has long had the devil as a regular, so the title is in capable hands, and this mid-2000s episode suits anyone who likes the show brisk and topical.
-
09
The Scoots
A later South Park, from the stretch when episodes often build on running storylines, so some jokes land harder if you’ve kept up. A good bonus pick once you’ve worked through the earlier ones.
-
10
Korn's Groovy Pirate Ghost Mystery
Take the title at its word: a groovy ghost mystery in the Scooby-Doo mold, with a pirate for the ghost and a nu-metal band’s name on the marquee. Loud, goofy and a good fit for anyone raised on mystery-gang cartoons.
-
11
Sons A Witches
Witches are on the bill, and the title bends a familiar insult into wordplay. A later-years South Park with the show’s usual topical bite, it suits viewers who like their Halloween irreverent.
-
12
Tegridy Farms Halloween Special
Randy Marsh’s farm gets a Halloween special of its own. It’s the lowest-rated South Park pick here, so save it for regular viewers who already know the farm.
-
13
The Halloween Night
This is a late chapter of a serialized, rotoscoped drama about grief, memory and a woman who can bend time, so start earlier in the series. It’s the pick here most likely to leave you thinking rather than laughing, and it’s strictly for adults.
-
14
Halloween on Spooner Street
Spooner Street is the Griffins’ own address, so the title brings Halloween home to Quahog. Family Guy’s cutaway-gag comedy suits viewers after an easy, jokey watch, and it is very much not for kids.
-
15
Peter, Peter, Pumpkin Cheater
A nursery rhyme gone sour, with Peter cast as the pumpkin cheat. It comes from the show’s much later seasons and ties for the lowest rating here, so it’s one for dedicated Family Guy fans rather than a first pick.
-
16
Trick or Treat
Odd Taxi is a Japanese animated mystery about a walrus cab driver in Tokyo, plotted like a puzzle box, so this trick-or-treat episode belongs after the earlier ones. Dry, dark and aimed squarely at adults.
-
17
Best Little Horror House in Langley Falls
The title riffs on a famous musical with a horror house in the lead role, and the setting is Langley Falls, home to a paranoid CIA dad and an alien in the attic. Loud, silly and packed with gags.
-
18
'F' Is for Halloween
Profane, tender and set in the 1970s, F Is for Family suits grown-ups who like their animated comedy rooted in real-life frustration. This one is from the first season, and it’s a firm no for kids.
-
19
A Sinister Halloween Scary Opposites Solar Special
Solar Opposites follows aliens living in suburban America, and this title scrambles the show’s own name for the occasion. Fast, irreverent comedy for adults who want their Halloween with a sci-fi twist.
-
20
The Solar Opposites Halloween Special Part 2: The Hunt for Brown October
A second-part special, so find part one first. The subtitle riffs on a Cold War submarine thriller, and this is really one for Solar Opposites fans who want the whole story rather than a first taste.
On Halloween, a grown-up cartoon gets to break its own rules and call it tradition.
Build a night around contrast: a loud South Park first, then something stranger from Smiling Friends or Solar Opposites. Save Undone and Odd Taxi for a night when you can start them from the first episode, since they tell one continuing story, and find the first part before the last Solar Opposites entry. For anything the kids can watch, the full watchlist has more Halloween episodes and movies for every age.
