A Creed is a particular group (or strain) of Hunters, in the White Wolf RPG Hunter: The Reckoning. The Creeds all have unique powers, which is the main division between the types. They are:
Martyrdom
Innocence
Judge
Avenger
Redemption
Visionary
Defender

Each Creed has their own Edges, and unique characteristics. For instance, the Martyrs are known to have a tendency to be masochistic, in that their Edges afford them great powers, at the expense of their bodies.

Creeds are exactly the same concept as the idea of Clans in Vampire: The Masquerade.
