The Buffyverse refers to the shared fictional universe in which the television series Buffy the Vampire Slayer and Angel are set. This term, originally coined by fans, has since been used even in the titles of published works, and adopted by Joss Whedon, the creator of the fictional universe. The Buffyverse has been expanded in licensed comics, novels, games, among others, although not always contributing to the canon history.
Similarly, the term Whedonverse is often used to refer collectively to Joss Whedon's works. Although, his other productions such as Firefly (2002–2003), Dr. Horrible's Sing-Along Blog (2008), Dollhouse (2009–2010), and The Cabin in the Woods (2012) do not share a universe with the Buffyverse.
