Olav is a Danish and Norwegian variant of Olaf. Like Olaf, it derives from the Old Norse name Áleifr, meaning "ancestor's descendant" from the elements anu "ancestor" and leif "inheritance, legacy". While Olaf and Olav are equally common in Norwegian, Olav is traditionally used when referring to Norwegian royalty. The name is associated with five kings of Norway, most notably Saint Olaf (Olaf II), who reigned from 1015 to 1028 and is credited with Christianizing the country. Etymology and History The name Olav is of Proto-Norse origin, reconstructed as *Anu-laibaz. It entered Old English as Ǣlāf (or Anlāf) and later as Olave. In Old Irish and Scottish Gaelic, it appeared as Amlaíb or Amhlaoibh, eventually giving rise to the modern version Aulay. The Latinized form is Olaus. The Danish variant is Oluf, while the Swedish equivalent is Olov or Olof. Other related names include Norwegian Ola and Ole (diminutives), Finnish Olavi and Uolevi, Estonian Olev, and Faroese Ólavur. A feminine form is Oline. Notable Bearers Numerous Scandinavian royals have borne the name. In Norway, King Olav V (1903–1991) reigned from 1957 to his death and was beloved for his modest demeanor. Olav remained a preferred spelling for Norwegian monarchs, besides Swedish King Olof Skötkonung and Danish King Oluf Haraldsen. The name also appears in Icelandic sagas featuring figures such as Olaf Tryggvason, indicating its enduring popularity across Scandinavia. Cultural Significance Given Saint Olaf's role as Norway's patron saint, Olav holds a central place in both religious and national identity. His feast day on July 29 is still observed in some Scandinavian Christian traditions. The spelling Olav especially resonates during celebrations of Norwegian Constitution Day and events linked to the Order of St. Olav, a Norwegian order of chivalry named after the saint.
