|Location||Eastern Eriador, west of Rivendell|
|Description||A wild forest on the north side of the East-West Road|
|People and History|
|Inhabitants||A few Trolls, if any|
|Events||Quest of Erebor|
On the hills of the Trollshaws were shallow caves, such as the Troll's Cave, and Mannish castles and towers.
They were the haunt of Trolls, especially after the fall of Arnor; Stone-trolls from "the mountains" came to the woodlands. This was the case of William who led Tom and Bert; having eaten a village and a half on their way, they complained about the scarcity of people in the area and instead had to make do with mutton. While they made their camp, they famously waylaid Bilbo and his companions who were on their Quest of Erebor. Thanks to the distractions of Gandalf, the Trolls were turned to stone by the Sun. Years later, Frodo and his companions traversed the woodland and found the Trolls' petrified forms on the way to Rivendell.
Shaws is an archaic word meaning "thicket, wood".
 Portrayal in adaptations
2007: The Lord of the Rings Online:
- Trollshaws is one of main regions of the game, lasting from the Last Bridge to the valley of Rivendell. The river Bruinen plays a prominent role there, with both Bruinen Gorges and the hills of Tal Bruinen being important landmarks. This area is inhabited by dozens of non-playable characters, who are involved in hundreds of quests.
- As in the book, the Company traverse the Trollshaws where they have a similar adventure with the Trolls.
