Ouroboros is an album by the Japanese noise musician Merzbow. It is named after the Ouroboros, a symbol depicting a serpent or dragon swallowing its own tail and forming a circle, and is dedicated to snakes.

The album is presented in a handmade eight-panel sleeve that can be rolled end-to-end to create an ouroboros. It is limited to 500 copies. The painting is an homage to Le Serpent by Ernst Fuchs.

An unreleased work called "samidara1" was played during an event at ohrenhoch in Berlin, Merzbow described it as "using the method of several granular synthesis programs and random process of the composition.", and referenced Graft, Chabo, Jigokuhen, and Ouroboros as having the same concept.
