Is Icelandic mythology Norse mythology?

Question

Is Icelandic mythology Norse mythology?

Answer 1

Yes....Norse, Viking or Scandinavian mythology comprises the indigenous pre-Christian religion, beliefs and legends of the Scandinavian peoples, including those who settled on Iceland, where most of the written sources for Norse mythology were assembled. Norse mythology is the best-preserved version of the older common Germanic paganism, which also includes the closely related Anglo-Saxon mythology. Germanic mythology, in its turn, developed from an earlier Indo-European mythology.

Answer 2

To a degree, Norse means it's relating to Iceland, Greenland, Sweden, Norway, Faroe Islands or Denmark.

Norse mythology would be broader, referring to mythologies of all of these places, not just Iceland.
