In the world, Sigurdur (Sigurdur , Sigurđur) is a rare masculine first name. The forename Sigurdur is characteristic of Iceland, where it is quite a common boy's name, Denmark, where it is a rare masculine name, and the United States, where it is an extremely rare principally masculine, but scarcely female name. Very seldom, Sigurdur is the last name as well as the forename.
