Meaning & origin

What does Thor mean?

Thor means “Thunder”.

Thor comes from the Old Norse name Þórr, meaning “thunder.” In Norse mythology, Thor is associated with the protection of gods and humans and with the hammer Mjöllnir. His stories belong to a much older Scandinavian tradition than the comic books and films that later adapted him for new audiences.

The name also exists outside mythology as a personal name, with Norwegian explorer Thor Heyerdahl providing a notable historical bearer. Tor is a closely related spelling used in Scandinavian languages. For parents considering Thor, the weather meaning and the mythological figure are inseparable parts of its background, while modern entertainment supplies an additional layer. The short spelling makes the name direct, but its story reaches through Scandinavian language, religion, exploration, and later popular culture.
