Metridium Fields is the major label debut by San Francisco-based doom metal outfit Giant Squid.

It is a re-recorded version of their album Metridium Field, which was released independently by the band two years earlier.

Fields was released on August 22, 2006, and brought the band critical acclaim and a devoted fanbase.

The title of the album and its closing track is named for Metridium, a genus of sea anemone.

The painting depicted in the album cover is Watson and the Shark by John Singleton Copley.
