Jansson is a Swedish patronymic surname, meaning "son of Jan." The name Jan itself is a form of Johannes, which ultimately derives from the Greek Ioannes and the Hebrew Yoḥanan, meaning "Yahweh is gracious" (see John). Jansson is one of many surnames with the Swedish patronymic suffix -sson, which indicates father-to-son inheritance. Etymology As a patronymic, Jansson originated from the father's given name Jan. In Sweden, such surnames were used alongside an inherited estate name, but over time became fixed family names. Similar to English names like Johnson, Swedish Jansson reflects the patronymic system that was common in Scandinavia. The name is most prevalent in Sweden and Finland (particularly the Åland Islands and Ostrobothnia), where it ranks among the most common surnames due to historical naming practices.
