Template:Article As with tie-in materials related to Star Trek, Star Wars, and other prolific sci-fi/fantasy franchises, most Buffyverse fans (and the show's creators themselves) acknowledge the Buffy and Angel TV episodes as absolute canon.
A few of the comics are considered by many fans to achieve canon.
- Tales of the Slayers and Tales of the Vampires are usually accepted as canon. They were written by writers of the Buffy and Angel television shows. Joss Whedon told a number of tales for these comic series. Other writers include Amber Benson, Ben Edlund, Jane Espenson, David Fury, Drew Goddard, Doug Petrie, and Rebecca Rand Kirshner.
- Fray, an eight-part comic series written by Whedon, is also largely accepted as a canonical work. The story is about a vampire slayer of the future named Melaka Fray and her discovery of what being a slayer means. In the Buffyverse, it seems that a powerful scythe used by Buffy will be found in centuries to come by Melaka. Whedon has also written an Angel comic book mini-series, Long Night's Journey.
- The Origin, a four-part comic series written by Christopher Golden and Dan Brereton had its canonality affirmed by Whedon who stated: "The origin comic, though I have issues with it, CAN pretty much be accepted as canonical. They did a cool job of combining the movie script (the SCRIPT) with the series, that was nice, and using the series Merrick." 
Several of the comics have been written by the scriptwriters of Mutant Enemy Productions, and do not often contradict any information from the Buffyverse canon. Some fans argue that any/all of these might also be considered canon. For example:
- Jane Espenson has written a number of Buffy comics, including the graphic novel Haunted and the one-shots Jonathan, and Reunion.
- Doug Petrie wrote Ring of Fire. He also wrote Double Cross, and Bad Dog, two stories found in the collection Food Chain.
