Infernäl Mäjesty is a Canadian heavy metal band, formed in 1986 and now based in Vancouver, British Columbia. They are best known for their debut album None Shall Defy, released in 1987. However, the 1998 re-issue by Displeased Records inspired them to get back together and they recorded a new album, followed by a European tour. They are still active.
They are not to be confused with HIM, who were previously called 'His Infernal Majesty'.
