|First appearance||Spirit Tracks (2009)|
|Region||Tower of Spirits|
- "Now there is but one temple left until all the tracks are restored. Once they are, we'll be able to enter the altar of the Demon King."
- — Princess Zelda
The Altar of the Demon King is a location from The Legend of Zelda: Spirit Tracks. It is found overlooking New Hyrule at the top of the Tower of Spirits. Malladus, the Demon King, is imprisoned within the altar by the powers of the Spirits of Good.
When Link and Princess Zelda restore the Tower of Spirits to its former state, they climb it in an attempt to prevent Chancellor Cole from reviving Malladus. They are stopped by Byrne, however, who challenges them to a duel. He is ultimately defeated, but the battle successfully stalls the heroes; Chancellor Cole successfully revives Malladus using Princess Zelda's body as a vessel on the Altar of the Demon King. Cole then betrays Byrne, and he and Malladus escape aboard the Demon Train. Anjean appears and tells Link and Princess Zelda that the only weapon with the power to stop Malladus is the sacred Bow of Light, which can purge Malladus from Zelda's body.
After Byrne reveals that the Compass of Light is needed to find Malladus, Link and Princess Zelda climb to the Altar of the Demon King again to reach two golden Eye Switches, that when activated, reveal a new area below the altar.
