Setianism comprises magical, philosophical and religious concepts related to the ancient Egyptian god Set.

The religious group that founded modern Setianism is the Temple of Set.

One can find the following defining concepts:

• is dedicated to the Egyptian god Set (or Seth)
• is an organizations which follows the Left Hand Path
• promotes a philosophy of individualism and self-exploration/mastery
• use Initiation as a primary tool
• have a priesthood or clergy
• keep private ‘members only’ information out of the public sphere
• employ admission policies that ensure only dedicated applicants are admitted to the organization

There is also a type of Gnosticism called Sethianism (after the third child of Adam and Eve of the Christian Book of Genesis), unrelated to Setianism.
