The Brotherhood of Steel (often abbreviated to BoS) is a fictional organization from Fallout, a post-apocalyptic video game and TV series franchise. Descended from a secessionist group of United States Armed Forces soldiers, the Brotherhood collects and preserves advanced pre-war technology. However, they are not generally known for sharing this knowledge, even if doing so would improve the quality of life among the people of the wasteland.

The Brotherhood faction has been present in every Fallout game to date.
