The hamingja was a type of female guardian spirit in Norse mythology. It was believed that she accompanied a person and decided their luck and happiness. Consequently, the name was also used to indicate happiness, and that is what it means in modern Icelandic. When a person died, the hamingja passed to a beloved family member and thus accompanied a family for several generations, continuing to influence their fortunes. It was even possible to lend one's own hamingja to a friend, as happened when Hjalti Skeggiason was about to leave on a perilous voyage and asked Olaf II of Norway to lend him his hamingja.

Sometimes hamingja is used to denote honor.
