"Half-trolls" was a term used to describe certain men from Far Harad who were loyal to Sauron. They are mentioned only once, during the Battle of the Pelennor Fields alongside the other man-allies of Sauron.
It is unknown if these individuals were members of a hybrid race, or if the term was intended as a simile.

The Hunt for Gollum
- Half-trolls appear in The Lord of the Rings: The Battle for Middle-earth II. Goblins, orcs and Uruk-hai were all created for the express purpose of war by dark powers. It is from this wicked tradition that the half-trolls were born. By crossing a troll and an orc there came into existence a rare but hefty breed of warrior. While trolls are strong but stupid, and goblins are numerous but frail, the marauders were strong and clever enough to eke out an existence wandering the empty wastes of the north. As a race hunted by the clever Dúnedain rangers, the marauders never found peace on their own, and as such their numbers remained few. It was in this way that the goblins pressed the half-trolls into the service of war. The marauders were welcomed into the caverns of the Misty Mountains upon the condition that they would don the twisted metal armor of the goblin army and fight when they were called upon. Now the goblins deploy the marauders where they fight best: in open battle against large opponents such as cavalry. When wielding a giant gnarled pike set for a charge, the brutal half-trolls are imposing and smart enough to use their weapons effectively. The half-troll swordsmen, who only appear in the game's expansion, The Rise of the Witch-king, are similar to the marauders but have swords instead of pikes. They have helmets and armor that are the same as the marauders', but more knight-like than goblin-Like.
- In Third Age: Total war, they are available to the Harad faction and are advanced light infantry known as troll-men of Harad.
- Half-trolls appear in The Lord of the Rings Strategy Battle Game as part of the Mahud faction of the Harad army. Revered by the Mahud for their physical prowess, they are used alongside Haradrim hosts during the War of the Ring.
