Arnlaugur is Icelandic, Norse in Origin.

Arnlaugur is an Icelandic masculine given name from Old Norse Arn-laugr. The first element, Arn- (from ǫrn), means “eagle,” a common Germanic name stem evoking sharp vision and courage; the second, -laugr, derives from laug, “vow, betrothal, consecration” (distinct from laug meaning “bath” in place-names). The composite sense is often interpreted as “eagle’s vow” or “one consecrated like an eagle.”

Attested within the medieval Norse naming tradition, Arnlaugur persists in Iceland - rare but preserved by the country’s preference for Old Norse forms - while related usage appears in Norway and the Faroes. Variants and close forms include Old Norse Arnlaugr, the Icelandic feminine Arnlaug (more common in Norway), and cognate relatives built on Arn-, such as Árni/Arne and Arnold. Contemporary Icelandic nicknames may include Laugi, with Árni sometimes used by association. Spelling is standardized as Arnlaugur in modern Icelandic nominative masculine, giving the name a distinctive, heritage-rich profile.
