Ever since Gravity Falls became a huge success, several forms of media have referenced the show in various ways.
Examples:
Comic Books- Artist Joe Quinones managed to slip references to Gravity Falls into books he did art for from both of the Big Two.
- In Batman and Robin Eternal #41, the Red Hood can be seen taking shots
◊ at an older Dipper and Mabel Pines during a fight scene. The Mabel lookalike even has a six-fingered hand for good measure. - The cover of Howard the Duck Vol. 5 #4 features Bill Cipher and the Six Fingered Hand design from the front of the Journals inside a book within the Sanctum Sanctorum, and Howard gets into an altercation with a Soos lookalike a few issues later.
- In Batman and Robin Eternal #41, the Red Hood can be seen taking shots
- My Little Pony: Friendship Is Magic (IDW): In Rarity's Issue 5 nightmare, she imagines her friends replacing her with a pony that looks similar to Mabel, including having the name Maybelle. Even the creator of Gravity Falls took notice of the Shout-Out when a preview of the comic was published.
- Arcanum Universe: Scarlet Heists: Professor Cerise has a flashback to the time he and Chloe played a round of CarnEvil all while Parker shouts Cute Biker's catchphrase of "Get 'em! Get 'em!"
- Chip 'n Dale: Rescue Rangers (2022): One of the "bootlegged" Toons that are freed near the end is Dipper drawn to look like a Smurf.

- AdVenture Capitalist: Houstan Pines and his design are a clear nod to Stan Pines. His power makes Gravity Booths cheaper.
- Among the clothes seen in a store in South Park: The Fractured but Whole include Dipper's hat, Mabel's sweater, and Grunkle Stan's fez.
- Homestar Runner's 2017 Halloween special, "Haunted Photo Booth", features Bubs dressed as Grunkle Stan. Clicking on him at the end causes a voice to say "Here comes the ThnikkaStan!", causing Bubs to respond "Shut up, Soos's Abuelita!"

- DuckTales (2017):
- In "The Living Mummies of Toth-Ra!" there's a Freeze-Frame Bonus of Bill Cipher in one of the hieroglyphs, albeit green instead of yellow. Bill was originally going to be green, like a dollar Bill, which makes sense in a show about the world's richest duck.
- "The Impossible Summit of Mt. Neverrest!": Huey questioning why the sun is drawn wearing glasses is the same question Dipper asked Soos.
- "Beware the B.U.D.D.Y. System!": Bill Cipher appears again in one of the sticky notes peppering Launchpad's windshield.
- MAD: In the "Pokémon of Interest" sketch, the commissioner mentions knowing every line of the show by heart. Later in his office, a bulletin board shows crude sketches of the Pines family, Soos, and Wendy. (Bill hadn't been introduced yet.)

- Star vs. the Forces of Evil:
- In "Starstruck", they go to tourist locations and see cameos of tourists◊ and Soos◊.
- In the episode "Friendenemies", we see above his desk Marco has a picture of a golden, six-fingered hand, with the number 3 on it.
