Treehouse of Horror 2026 spoofs Disney’s Nightmare Before Christmas

The Simpsons’ Treehouse of Horror XXXVII airs Sunday, Oct. 25, on Fox, 36 years to the day after the first one. It opens with a Simpsons version of The Nightmare Before Christmas.

The Simpsons are doing “The Nightmare Before Christmas” this Halloween.

“Treehouse of Horror XXXVII” airs Sunday, Oct. 25, on Fox, Variety reported. It opens with a “Simpsons” and “Nightmare Before Christmas” mashup, with Simpsons versions of the Nightmare characters, made by Stoopid Buddy Stoodios, the studio behind “Robot Chicken.”

The date’s a fun one, too. The very first “Treehouse of Horror” aired Oct. 25, 1990, according to Disney+. So this year’s lands 36 years to the day later.

When is Treehouse of Horror 2026 on?

Sunday, Oct. 25, on Fox, according to Variety.

“The Simpsons” airs Sundays at 8 p.m. on Fox, and new episodes stream the next day on Hulu, Variety reported with the Season 38 premiere.

And that Sunday is wide open on Fox for a reason. Fox has the World Series this year, and Sunday, Oct. 25, is one of the series’ scheduled off days, Major League Baseball’s postseason schedule shows.

What are the Treehouse of Horror XXXVII segments?

Showrunner Matt Selman laid out three stories for Variety, after that Nightmare opening.

• The one with “The Husbands”: Based on Holly Gramazio’s novel, Homer walks into the shed and comes out as a different husband for Marge. Suddenly she’s married to Lenny. Or Kang and Kodos. Tiffany Haddish guest stars as Marge’s best friend.

• “Freaky Friday” meets “Pet Sematary”: Homer accidentally kills Bart and the dog and buries them. They come back with their bodies switched.

• The driver’s ed one: Homer vanished years ago, and teenage Bart and Lisa find out evil witch versions of Patty and Selma have trapped him in endless murderous driver’s ed films.

Haddish’s character “lectures Marge about dating, and it’s like a stand-up set,” Selman told Variety.

Fox hasn’t released official segment titles yet.

Is The Simpsons a Disney show?

Sort of. It’s complicated, but not that complicated.

Disney bought 21st Century Fox in 2019, and that deal brought the studio that makes “The Simpsons” along with it. The show still airs on the Fox network, which is a separate company Disney didn’t buy.

That’s why it streams on Disney+ and Hulu. So this month, a show Disney owns will spoof a movie Disney owns, on a network Disney doesn’t own.

How many Treehouse of Horror episodes are there?

It depends how you count.

There have been 36 numbered “Treehouse of Horror” episodes so far, through “Treehouse of Horror XXXVI” in Season 37, according to Disney+’s own guide. Add “Thanksgiving of Horror” and two “Treehouse of Horror Presents” specials, and Disney+ counts 39 Treehouse-branded episodes.

So XXXVII will be the 37th numbered one. By Disney+’s math, it’s the 40th Treehouse episode overall.

Here’s Disney+’s official supercut of Homer losing it in past Treehouse episodes:

Where can you watch every Treehouse of Horror?

Seasons 1 through 36 of “The Simpsons” are on Disney+, including a Treehouse of Horror collection, according to Disney+.

Season 37, which has last year’s “Treehouse of Horror XXXVI,” is on Hulu and Hulu on Disney+ for bundle subscribers. Disney+ says that season is planned to arrive on Disney+ this fall.

The new one, XXXVII, should stream on Hulu the day after it airs, the same as the rest of Season 38.

What else is happening with The Simpsons for Halloween?

There’s a Jack in the Box meal. The chain has a “Munchie Meal of Horror” with six glow-in-the-dark collectible cups, Variety reported. Selman said the cups sold out fast.

The new movie moved. The next “Simpsons” movie is now set for Sept. 3, 2027, moved from July 23, Variety reported. Selman said the working title is “New Simpsons Movie.”

What are some fun facts about Treehouse of Horror?

The name came from the first one. The 1990 original used a treehouse as the place the kids told their scary stories, and the name stuck, Disney+ notes.

Each one is an anthology. Numbered episodes usually tell several shorter stories. The “Presents” episodes tell one longer story instead, according to Disney+.

No watch order needed. Disney+’s guide says each one stands alone, so you can jump in anywhere.

Jack Skellington has been through a lot. Getting drawn with an overbite might be a new one.
