Nilsen is Norwegian, Scandinavian in Origin.

Nilsen is a Scandinavian patronymic turned surname and, in modern use, an uncommon given name, used chiefly in Norway. It literally means “son of Nils,” with the -sen suffix denoting descent; Nils/Niels are Nordic forms of Nicholas, from Greek Nikolaos (nikē “victory” + laos “people”). Common cognates and spelling variants include Norwegian/Danish Nielsen, Swedish Nilsson and Nilson, as well as Anglicized forms Nielson, Neilson, Nelson, and Nelsen; rarer Norwegian spellings like Nilssen also appear. Feminine historical counterparts were Nilsdatter (Norwegian/Danish) and Nilsdotter (Swedish).

Across Scandinavia, patronymics prevailed for centuries before becoming fixed hereditary surnames in the 19th century, which cemented Nilsen as a family name. Migration spread it to the Americas and beyond, sometimes prompting simplified spellings. As a given name, Nilsen remains rare but usable, conveying Nordic heritage and the uplifting sense of “victory of the people.”
