Magnus, meaning "great" in Latin, was sometimes used as a first name among Romans but was not particularly common among them. The best-known Roman bearing the name was the third-century usurper. The name gained wider popularity in the Middle Ages, various European peoples, and their royal houses, being introduced to it upon being converted to the Latin-speaking Catholic Christianity. This was especially the case with Scandinavian royalty and nobility.

As a Scandinavian forename, it was extracted from the Frankish ruler Charlemagne's Latin name "Carolus Magnus" and re-analyzed as Old Norse magn-hús = "power house".
