Norse mythology is a collection of beliefs and stories shared by Northern Germanic tribes. It had no one set of doctrinal beliefs. The mythology was orally transmitted in the form of poetry and modern knowledge about it is mainly based on the Eddas and other medieval texts written down during and after Christianization.

Some aspects of Norse mythology passed into Scandinavian folklore and have survived to modern day. Others have recently been reinvented or reconstructed as Germanic Neopaganism. The mythology also remains as an inspiration in literature (see Norse mythological influences on later literature) as well as on stage productions and movies.
