In Game of Thrones / A Song of Ice and Fire, when people talk about there being “nine kingdoms,” they’re really talking about the nine regions that make up the so‑called Seven Kingdoms of Westeros.

Why “Seven Kingdoms” but Nine?

Originally, before Aegon the Conqueror, there were seven independent kingdoms in Westeros.

After Aegon’s conquest, the political map changed:

  • The Crownlands were carved out around King’s Landing as the royal demesne.
  • The old Kingdom of the Isles and the Rivers was split into two separate regions: the Iron Islands and the Riverlands.

That left nine regions under the Iron Throne, even though the old name “Seven Kingdoms” stuck.

The Nine “Kingdoms” (Regions) Egg Lists

In A Knight of the Seven Kingdoms , Egg spells them out as nine:

  1. The Crownlands – The royal territory around King’s Landing, directly ruled by the king on the Iron Throne.
  1. The North – Vast, cold region ruled historically by House Stark from Winterfell.
  1. The Vale of Arryn – Mountainous eastern region ruled by House Arryn from the Eyrie.
  1. The Riverlands – Fertile central river country later ruled by House Tully from Riverrun.
  1. The Iron Islands – Harsh, seafaring islands of the ironborn, ruled by House Greyjoy in the main series era.
  1. The Westerlands (the Rock) – Rich western region full of gold mines, ruled by House Lannister of Casterly Rock.
  1. The Reach – Mild, fertile southern region famous for agriculture and knights; historically ruled by House Gardener, later House Tyrell.
  1. The Stormlands – Storm‑battered southeast coast, originally under House Durrandon, later House Baratheon of Storm’s End.
  1. Dorne – Hot southernmost region, ruled by House Martell of Sunspear, whose rulers style themselves as princes rather than kings.

So when someone asks “what are the nine kingdoms in Game of Thrones,” they usually mean this list of nine regions that together form the realm still traditionally called the Seven Kingdoms.
