Mindflayer is a noise rock band from Providence, Rhode Island, made up of Brian Chippendale (of Lightning Bolt) and Mat Brinkmann (of Forcefield) which was formed out of Fort Thunder.

Much of Mindflayer's identity, including the band name, are obscure Dungeons & Dragons references. The name of the band refers to psionic creatures in the Dungeons & Dragons universe, Illithids, commonly referred to as "mind flayers." The covers of Take Your Skin Off and Die & Mold Services also resemble the Illithid's squid-like faces. The title to the band's fourth album, Expedition to the Hairier Peaks, plays on the popular Dungeons & Dragons module title, Expedition to the Barrier Peaks. Mat Brinkman uses a circuit bent analog synthesizer.
