The Power Cosmic is the fourth album by the English metal band Bal-Sagoth, released in 1999.

The album also marks a personnel change, as the trio became a quintet: Mark Greenwell joined on bass, which freed up Chris Maulding to focus on guitars, while Dave Mackintosh (later of the power metal band DragonForce) would handle drums, thus enabling Johnny Maulding to concentrate on keyboards and synthesizers.

The album focuses on Zurra, a rogue demigod released from his imprisonment beneath the Mare Imbrium who searches space to reassemble the powerful artifact known as the Empyreal Lexicon.

The song "Of Carnage and a Gathering of the Wolves" takes place in Darkenhold forest, a location last referenced in track 9 of the album Starfire Burning Upon the Ice-Veiled Throne of Ultima Thule.

The album title, The Power Cosmic, is a reference to the superpowers possessed by Galactus and the Silver Surfer, and was chosen primarily because Byron Roberts is a great admirer of Marvel Comics and particularly the works of Jack Kirby, as mentioned in the 50th issue of the magazine The Jack Kirby Collector.
