Headkase was an Australian avant-garde metal band from Brisbane, Queensland, formed in 2001.

Headkase consisted of six members, and are known for theatrical and energetic stage shows, circus-themed masks and facepaint.

After forming in early 2001, Headkase self-released a demo/EP titled The Beginning and eventually went on to open for such touring acts as Hed PE, Killing Joke, Skinlab, Jerk, Blood Duster, Devolved and Testeagles.

Reasons for the band disbanding are unknown, however drummer Todd Hansen has gone on to play for Melbourne outfit King Parrot.
