This article describes a concept which is mentioned in J.R.R. Tolkien's works, but was never given a definite name.
- "Yes, I am afraid trolls do behave like that, even those with only one head each."
- ― Roast Mutton
Two-headed Trolls might have been a legendary race of Trolls, whose possible existence is fleetingly suggested in a chronicle of the Quest of Erebor, commenting on William wiping his lips on his sleeve.
C.S. Lewis mentioned the Ettins of Ettinsmoor in Narnia, some of which have two heads. In many later fantasy settings, but also some adaptations of Middle-earth, there are two-headed monsters, which usually are called "ettens" (q.v.).
 Portrayal in adaptations
1982-97: Middle-earth Role Playing:
1995-8: Middle-earth Collectible Card Game:
- "'Two-headed' Troll" is a Warrior Ally for evil players.
1998-2004: Middle-earth Online:
- Ettins, a race of two-headed trolls, was intended to be included in the game.
- Ettens resemble the Hill-trolls, but they possess "not one but two long heads". The solitary creatures, a result of an ancient experiment by Morgoth, live almost exclusively in the Ettenmoors.
2017: Middle-earth: Shadow of War:
- The Overlord of the Núrnen region of Mordor is an Olog named Ranger, who poses as a Troll with two heads. In reality, the second head is that of the Uruk Ratbag the Coward, who is riding on Ranger's back and wearing a large helmet to conceal his identity.
