Etymology

Rasmussen is a Danish and Norwegian patronymic surname formed from the given name Rasmus plus -sen, meaning “son of.” Rasmus is a Scandinavian form of Erasmus, ultimately from Greek *erasmios*, “lovely” or “beloved.” So the surname originally identified someone as the son of a man named Rasmus.

History

The name is especially common in Denmark and Norway, where patronymic surnames of this type became fixed family names in the 18th and 19th centuries. It also spread widely through emigration to North America and other English-speaking countries. In the United States it is found among descendants of Danish and Norwegian immigrants, and sometimes appears in records with simplified or variant spellings.
