Kjartanur is Icelandic, Norse in Origin.

Kjartanur is a modern Nordic elaboration of Kjartan, adding the productive -ur masculine ending seen in Icelandic-style names. Kjartan itself is the Norse adaptation of Old Irish Muirchertach, transmitted in the Viking Age via the form Myrkjartan. The Irish elements muir "sea" + certach/ceartach "ruler, champion" yield the common interpretation "sea-ruler" or "sea-warrior." Related forms include Kjartan (standard Icelandic, Faroese, Norwegian), Kiartan (Anglicized), and the Irish originals Muirchertach and its Anglicization Murtagh.

The name entered Nordic use through Norse-Gaelic contact and gained literary prominence in the Icelandic Laxdæla saga with the beloved hero Kjartan Ólafsson. Kjartan remained in Icelandic and Faroese name stock, seeing renewed popularity in the 19th–20th centuries with interest in saga names. Today usage is concentrated in Iceland; Kjartanur appears occasionally as a creative variant. Informal nicknames such as Kjarti or Kjarri may be encountered in Icelandic.
