Giant

Giants were a huge, humanoid race who generally inhabited the southern and northern lands of the World of Narnia. It is possible that the world of Charn was also home to Giants, like the ancestors of Empress Jadis.

In the Narnian World, Giants were divided into three groups: Archenlanders (southern brave giants), Harfangers (northern intelligent Giants), and Narnians (southern gentle Giants).

Archenlander
These giants happen to be brave and also gentle ones in the land of Archenland. They are very loyal to the Kings and Queens of Archenland as perfect allies. These giants fought in the Battle of Anvard with the Narnians to stop Prince Rabadash and the Calormene army.

Harfanger
The civilised Giants of the Great Northern Plain lived in the castle of Harfang. These giants were the descendants of an ancient race of extremely intelligent giants who ruled a great kingdom in the far north, of which the Great Northern River was only the southern boundary. The Harfangers were one of a few groups of Giants who had a system of government and a societal structure. They were renowned for their great Autumn Feast, at which they ate many things, including man pie. Their hunting parties ranged as far south as northern Narnia.

Narnian
Southern or Narnian Giants were kindly, though not known for cleverness. Notable giants include Rumblebuffin, Wimbleweather, and Stonefoot. They fought on the Narnian side in the Battle of Beruna and at the Siege of Anvard in the Golden Age of Narnia.

Behind the Scenes
In the 2005 film of The Lion, the Witch, and the Wardrobe, ten Narnian giants were seen in the White Witch's army in the First Battle of Beruna. They were never seen fighting the Narnian army and it must've been said that since they are gentle in the land of Narnia, they fought with the Narnians against the White Witch's army. In the Prince Caspian video game, two giants were mentioned where they fight with the Old Narnians as they defend Cair Paravel from the invasion of the Telmarines. There names are called Stonehorn and Cliffhorn who happen to be brothers that defended their lives at Cair Paravel.
