Open Secrets in Western Animation.
- DuckTales (2017): Fenton tries to keep his identity as Gizmoduck a secret from others, but he's so bad at it that pretty much everyone's figured it out by the end of the show (with the notable exception of Darkwing Duck).
- The Emperor's New School continues the gag from its original film. "To the not-so-secret lab!"
- A House of Mouse episode had Clarabelle about to reveal a big secret and everybody in the Club is worried it's going to be his/her secret. By asking Clarabelle what the secret is, they accidentally reveal their own secrets to Clarabelle instead: Mickey reveals he does something with his ears so they look the same no matter angle you see them from, while Donald reveals he's part goose. When it's Goofy's turn, he disregards Mickey and Donald's secrets since everybody already knows them but his secret, according to him, is bigger: He's rather clumsy. And can prove it!
- Kim Possible:
- Area 51 is rumored to be a secret alien research base. The main characters eventually arrive at Area 51 to discover that it actually is a secret alien research base, but with a twist — authorities let the secret out, knowing that the public would believe it to be wild rumors, thus keeping the "secret" safe.
- Most of the villain lairs, which are obviously intended to be secret and untraceable by the villains themselves but are easily found by a ten-year-old boy, Global Justice, and/or pretty much anyone the plot wants to know. Particularly notable with Dementor and Drakken, who really push the "secret lair" schtick. In one memorable case, Drakken's lair was found no problem by his mother. Like everything, Lampshaded — this time by Motor Ed.Ed: Dude, seriously, what type of secret hideout is this? Everyone knows you live here, man!
Drakken: One magazine subscription and suddenly everyone's got your address...
- Played with in an episode of Adventure Time where Finn has acquired a stack of tapes that the Ice King is trying to hide. He and Jake decide to have a secret party to watch them, so Jake puts up a ton of fliers to announce they are having a private secret-tape watching party and nobody should come. The Ice King finds the fliers and tries to crash the party, upsetting Jake who was "very clear in the fliers" that nobody was invited.
- In King of the Hill, pretty much everyone except Dale knows that his wife Nancy is cheating on him with her "massage therapist" John Redcorn, who is Joseph's real father. Even Bobby is in on the secret (Joseph himself seems to genuinely be just as clueless as Dale, though). It eventually comes out that Peggy didn't know until Hank tells her, leading him to bring it up to his friends, who immediately pretend they don't know what he's talking about.
- In the Looney Tunes short The Great Piggy Bank Robbery, Daffy Duck plays a detective who finds the gangster's secret hideout by taking a streetcar (driven by a mustached Porky Pig) marked "TO THE GANGSTER HIDEOUT" with multiple signs.
- In the early episodes of Miraculous Ladybug, very few people were aware of Marinette's crush on Adrien, and even Alya telling Nino about it was supposed to be a secret. By season 4, the only person not aware of Marinette's crush on Adrien is Adrien himself.
- The My Little Pony: Friendship Is Magic episode "Green Isn't Your Color" had Spike confess his deepest secret to Twilight and Pinkie... His crush on Rarity. A secret everyone in town was already aware of... except for Pinkie of course.
- The Raccoons: In "The One That Got Away!", Bert and Cedric show Bentley their fishing spot that they've been keeping a secret and make him promise to keep it a secret as well. However, it's later revealed that Ralph, Melissa, Cyril, and even Mr. Willow are already aware of the location. Cyril also believed it was a secret to him until he found out his father fished there as well.
- The Simpsons: The Stonecutters, the local Brotherhood of Funny Hats, are generally treated as a secret organization in the episode they appear in. On the other hand, their membership seems to include just about every recurring male character in Springfield. It makes it even sillier that it took Homer so long to find out the organization existed, when, for instance, Lenny, Carl, Moe, and Barney were all members, and that's just in Moe's Tavern.
- The Venture Bros.: The Sovereign is the leader of the guild, and his identity is a well-kept secret...except almost everyone knows he's David Bowie. Yes, David Bowie. A later episode then revealed he isn't David Bowie, but a shapeshifter who knew him.
