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.

While some tracks originated from "little jams" the band would do at sound check, the majority of the album was created in time dedicated to writing new material. Gallagher adds that “[m]usically speaking, Panopticon came out a couple of ideas that had been kicking around in our heads for some time, but the bulk of it was composed after we decided that it was time to do a new record. The writing process consisted mostly of an individual starting the core of an idea for a song at home then either pairing off with someone else or bringing it to everyone where it was worked on and refined until everyone was satisfied”. According to Jeff Caxide, this process was significantly different from that of previous Isis albums, as “everyone wrote a lot on this record. There is not one
