Beavis and Butt-Head is an American adult animated sitcom created by Mike Judge. The series follows Beavis and Butt-Head, both voiced by Judge, a pair of teenage slackers characterized by their apathy, lack of intelligence, lowbrow humor and love for hard rock and heavy metal. The original series juxtaposes slice-of-life short subjects—in which the teens embark on low-minded misadventures in their Texas town—with the pair watching and commenting on music videos.

Judge developed the pair when financing and making his own animated shorts; two of these films, including Frog Baseball, were broadcast by MTV's animation showcase Liquid Television. The network commissioned a full series, which over its seven seasons became its most popular program. The original series ended in 1997, but has been twice rebooted, first in 2011 for MTV, and again in 2022 for Paramount+. Starting in 2025, new episodes will air on Comedy Central.

During its initial run, Beavis and Butt-Head received critical acclaim for its satirical, scathing commentary on society, as well as criticism for its alleged influence on adolescents. The characters became pop culture icons among Gen. X viewers, with their sniggering and dialogue becoming catchphrases. The series was adapted into a theatrical film, the commercially successful Do America (1996), as well as a sequel, Do the Universe (2022). The franchise also spawned a comic book series, video games, books, an album, and more.
