Christensen is a Danish and Norwegian patronymic surname meaning "son of Christen 1". Christen is a Scandinavian form of Christian, which derives from the Latin Christianus, meaning "a Christian" and ultimately from Christos 1. The name Christian became widespread in Scandinavia after the introduction of Christianity, and in Denmark it was borne by ten kings from the 15th century onward, further cementing its popularity. As a patronymic, Christensen follows the common Nordic naming tradition of adding -sen (or -son) to the father's given name, indicating lineage. While the surname is particularly common in Denmark and Norway, it has also spread internationally, especially to English-speaking countries through emigration from Scandinavia.
