A male Biblical name meaning healer, Asa is also an international gem. In Japanese, it means "(born in the) morning". And in Scandinavia, where it's generally spelled Åsa or Ása and pronounced O-sa, it's a popular diminutive form of Old Norse names beginning with the element áss "god".

Associated with the mononymic Icelandic singer and her iconic swan dress.

Bjork

Bjorn is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks in large part to tennis great Björn Borg, winner of five consecutive Wimbledon singles titles and six French opens and something of a rock star figure.
 
Bjorn has been in use since the days of the Vikings, but got a boost in popularity when Borg ruled the courts. There have also been other notable Bjorns in various fields in Sweden, Norway and Germany, ranging from the first king of Norway to a member of the pop group ABBA.
 
And if you do pick this name for your son, your baby Bjorn can be carried around in a Baby Bjorn.

Bjorn

Bera

Dalla

Darra

With Norse (and pseudo-Norse) names such as Thor, Odin and Magnus growing in popularity, this one, which refers to warriors destined for Valhalla on account of their bravery, might have some appeal outside Scandinavia. Its slightly Eeyore-ish sound is balanced out by connections to some major historical figures, including a Norwegian prime minister.

Einar

Eirik

A simple and attractive feminization of the Nordic name Finn.

Finna

Lovers of Loki who don't appreciate the overt mythological reference might like this unusual Icelandic name.

Floki

The dynamic personality and paintings of Mexican artist Frida Kahlo have inspired growing numbers of parents to resurrect this form of the name. It does much better in certain European countries, especially in Denmark and Norway. The Frieda and Freida spellings were more popular in the US until the middle of the 20th century.

Frida

A key figure in Norse legend and a traditional Scandinavian favorite making inroads here.

Gunnar

A traditional Nordic name, Helga was extremely popular throughout Scandinavia in the 19th and early 20th centuries. In Germany, it was a Top 10 pick from 1924 to 1943. And it still ranks in the Icelandic Top 50 today.

 In the English-speaking world, Helga has been associated with a series of unfortunate characters in popular culture, from the wife of Hägar the Horrible in the comic strip of the same name, to Helga Pataki from the kids' TV show Hey Arnold!. But more recent, more positive Helgas – like Helga Hufflepuff, one of the four founders of Hogwarts, and a character in the drama series Vikings – could redeem the name.

 Helga's Russian cognate, Olga, is a classic there, and still ranks in the Russian Top 50 today.

Helga

A Scandinavian up-and-comer taken directly from Norse mythology. Iðunn was the goddess of apples, fertility, and youth. Idun is another common spelling.

Idunn

Ing was a powerful Norse god whose name inspired several modern variations -- though Inga has become a caricatured Scandinavian choice. 

Inga

Kara and the soundalike (though not necessarily related) Cara are among the most multi-cultural names around. Cara has roots in Latin, Italian, Irish, Spanish, and Portuguese, and Kara can be viewed as simply as K-starting version of Cara. 

But Kara is also uniquely a Norse mythology name, drawn from the name of a valkyrie meaning "wild stormy one".. Kara was a Valkyrie, lover of Helgi, who charmed his enemies in battle by enchanting them with song.

Both Cara and Kara peaked in the 1980s but Kara remains more popular than the Cara variant.

Kara

A Top 10 name in Iceland, where it is also the name of an active volcano.

Katla

An old Norwegian name derived from ketill, the word for a cauldron or kettle used to catch sacrificial animal blood in ancient Norse pagan rituals. Today the name is more often seen in its Kjetil and Kjell variations for boys, and Katla for girls.

Ketil

Leif is one of the most recognizable <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf. 
 Leif Erikson, son of explorer Eric the Red, was the first European to land in North America--some five hundred years before Columbus. Centuries later, the name became associated in the U.S. with 1970s teen idol Leif Garrett, the name peaking on the charts at Number 654 in 1970, dropping off completely in 1987. It climbed back onto the Top 1000 in 2014.
 Pronounced LAYF in its Scandinavian milieu, Leif and Lief are sometimes pronounced as Leaf in English-speaking countries. Joaquin Phoenix was for a time known as Leaf, in keeping with the <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a> of his siblings.
