Focalor is a powerful Great Duke of Hell, commanding three or thirty legions of spirits. Focalor is mentioned as the forty-first of the 72 goetic demons. Focalor is depicted in the form of a man with a griffin's wings, kills men, drowns them, and overthrows warships; but if commanded by the conjurer he will not harm any man or thing.

Focalor has power over wind and sea, and had hoped to return to heaven after one thousand years, but he was deceived in his hope.

One of the three archdemons, Lucifuge Rofocale, has his second name as an anagram of Focalor, implying an intellectual relationship.
