Comets on Fire were an American noise rock band from Santa Cruz, California, United States.

The band was formed in 1999 by guitarist and vocalist Ethan Miller and longtime friend bassist Ben Flashman, who were seeking to create rhythmically and sonically intense music that paid no attention to categorizations.

In 2006, they released their fourth album Avatar which showed the band turning away from their psychedelic noise jams for a more subdued sound that ventures close to classic rock at times.

In the intervening period Ethan Miller began focusing attention on his Howlin' Rain project, and Noel von Harmonson joined Sic Alps.
