Panopticon is the third full-length album by Los Angeles, California based post-metal band ISIS, released by Ipecac Recordings in 2004. The album's title is derived from philosopher Jeremy Bentham's panopticon prison ideal and philosopher/historian Michel Foucault's later allegorical appropriation of the concept. The liner notes also include quotes from technology writer Howard Rheingold and futurist Alex Steffen; as a concept album, Panopticon's focus is on the proliferation of surveillance technologies throughout modern society and the government's role in that spread.

Isis was an American post-metal band formed in Boston, Massachusetts in 1997 by guitarist and vocalist Aaron Turner, bassist Jeff Caxide, vocalist and electronic instrumentalist Chris Mereschuk and drummer Aaron Harris. After a demo and the EP Mosquito Control were recorded by the original lineup, Mereschuk was replaced by Jay Randall in 1999, who joined the group alongside guitarist Michael Gallagher. Jay Randall would later be replaced by guitarist and keyboardist Bryant Clifford Meyer after the recording of Red Sea. With roots in hardcore punk and doom metal, the band borrowed from and helped to evolve the post-metal sound pioneered by bands such as Neurosis and Godflesh, characterized by lengthy songs focusing on repetition and evolution of structure. Isis disbanded in June 2010, just before the release of a split EP with the Melvins, reforming only once in 2018 as Celestial for a one-off show to pay tribute to Caleb Scofield.
