Kaysen is a modern American given name with surname roots. As a family name, Kaysen is Scandinavian, formed with the Danish/Norwegian patronymic -sen, literally “son of Kay” (Kay/Kaj, a form of Kai; Kai is often linked to Latin Gaius, perhaps “rejoice”). In contemporary U.S. naming, Kaysen also functions as a creative respelling of the English surname-given Cason/Cayson, aligning with the popular -son ending.

Use as a first name surged in the 2010s in the United States, and it remains rare but recognizably modern. Common variants include Kayson, Kaison, Kason, and Cayson; less common spellings are Kaysin and Kaysun. The core meaning is interpreted as “son of Kay/Kai,” with an optional classical echo of “rejoice” via Gaius. Kaysen reads primarily masculine in American data but is technically unisex, prized for its crisp cadence and contemporary, surname-style appeal.
