The Cobble Kingdom is a location mentioned in the The Legend of Zelda: Phantom Hourglass. A once great civilization, the Cobble Kingdom mysteriously vanished into obscurity sometime prior to the events of Phantom Hourglass.

Situated on the Isle of Ruins, the island was likely named this after the Cobble Kingdom crumbled, the Cobble Kingdom was ruled by King Mutoh. To keep peace within the kingdom, Mutoh named four mighty warriors, Brant, Bremeur, Doylan, and Max, the Four Knights of the Cobble Kingdom.

The Cobble people were excellent engineers, able to build massive pyramids and elaborate tombs. Zauz, a descendant of the Cobble people, also tells Link that his ancestors were excellent blacksmiths, able to create the finest of swords to defend the World of the Ocean King from evil. Finally, the fortune-teller Astrid is a descendant of the Cobble Kingdom, perhaps indicating that the people were skilled in the area of prophecy.

Mysteriously, however, the Cobble Kingdom vanished from history. No explanation on this is ever given, but when Link visits the Isle of Ruins he finds the remains of the kingdom, Mutoh's Temple, hidden below the surface of the water on the island. When Link obtains the King's Key from the ghost of Doylan, he is able to lower the water level and enter Mutoh's Temple. Here, he encounters and slays Eox, a gargantuan stone golem that is disturbing King Mutoh's slumber in the afterlife. Once Link does this, the ghost of King Mutoh gives him the Pure Metal, Aquanine, needed to forge the Phantom Sword that is needed to ultimately slay Bellum.

The Cobble Kingdom was studied extensively by the late adventurer McNey during his lifetime. He documented many topics including King Mutoh, the Four Knights of the Cobble Kingdom, Aquanine and even the Uncharted Island in his series of books known as the Explorer's Compass.

The Cobble Kingdom is similar to ancient Egypt in both architecture and social normality.
