Canon is the official story of The Simpsons universe. Due to the episodic nature of The Simpsons and a floating timeline, some episodes are considered non-canon because they do not match up with the existing and future story and lore.

Floating timeline

A floating timeline is often used in media where the characters do not age. The floating timeline is used to keep stories relevant for modern times without having the characters age up. Since The Simpsons has been airing since 1989 without the characters aging, the timeline adjusts to keep up with the current year. As such, characters have been different ages in different time periods. For example, Homer has been a young adult in the 1990s, as seen in the season 19 episode "That '90s Show" and a teenager in the 1990s, as seen in the season 32 episode "Do PizzaBots Dream of Electric Guitars?". These episodes are considered canon, just canon at different time periods.

Separate canons

The Simpsons executive producer Matt Selman has said that he considers episodes to take place in "its own little universe". This allows them to write about an "aspect of Springfield that hasn’t been examined before."[1] This means that there's no official canon within the show.

However, some events from episodes do carry forward to other episodes. Major changes happen in the show that continue to other episodes. Big examples include Maude Flanders' death in the season 11 episode "Alone Again, Natura-Diddily", the Ned Flanders and Edna Krabappel relationship in the season 22 episode "The Ned-liest Catch", and Comic Book Guy's marriage to Kumiko Albertson in the season 25 episode "Married to the Blob". These permanent changes imply that there is a canon to The Simpsons.

Anthology episodes

Anthology episodes are episodes made up of multiple mini-stories. An example of these is the long-running Treehouse of Horror series. Most anthology episodes have a framing device used for the characters to tell the stories. These parts of the episodes are considered canon whilst the stories are considered fictional within the universe. Anthology episodes without a framing device, such as a majority of the Treehouse of Horror episodes, and the season 31 episode "Thanksgiving of Horror", should all be considered non-canon.

Comic stories and books

A majority of comic stories and books fit in with The Simpsons universe. However, episode canon comes before comic and book canon, so if an episode contradicts a comic story or book, the episode is considered canon but the comic or book isn't.

Video games

All video games should be considered non-canon to the franchise.
