A patronymic surname-name meaning "son of Erik," with Erik from Old Norse meaning "eternal ruler."
Ericson is a patronymic surname of Old Norse origin, meaning quite literally 'son of Eric' — with Eric itself derived from the Norse Eiríkr, combining ei (ever, always) and ríkr (ruler, powerful), yielding something like 'eternal ruler' or 'ever mighty.' The name Eric was widely used among the Norse and Scandinavian peoples from the Viking Age onward, generating patronymic forms across every country touched by Nordic culture: Eriksson in Sweden, Ericsen in Denmark, Ericson and Erickson in anglicized American forms. The most famous bearer of this surname lineage is Leif Ericson, the Norse explorer who, around 1000 CE, led the first known European expedition to North America — reaching a place he called Vinland, believed to be in present-day Newfoundland.
Leif Ericson Day is observed on October 9th in the United States and several Scandinavian countries, and his name has become shorthand for the audacious spirit of exploration and discovery that characterized the Norse world at its height. The surname also marks the family of Erik the Red, Leif's father, who established the first European settlement in Greenland. As a given first name, Ericson is uncommon but not unprecedented — families sometimes lift surnames into the first-name position to honor Scandinavian heritage or a specific ancestor.
It carries a strong, open sound and an inherently historical weight, the name of explorers and dynasts compressed into a single word. Parents who choose it for a first name tend to want something that signals lineage, adventure, and a northern strength of character.
