Quick Links
Fallout 76is an extremely fun online game that allows players to take on the role of a Vault Dweller exploring Appalachia 25 years after The Great War devastated the area.
In those 25 years, factions have come and gone throughout the region. In fact, when the game was released, there were no NPCs. Instead, the player would roam Appalachia, trying to finish the work of past factions (though this has changed). Here’s a list of all the factions and how to join those that the player is able to join in the game.

All Factions In Fallout 76
There are many factions located throughout Appalachia (and even beyond it) that players can interact with. Here’s a breakdown of those factions, where they are, whether they can be joined, and when they were introduced.
Some factions will allow players to help them out a ton, but they are never official able to join them.
