"Do I have Viking DNA?" is one of the most common questions people ask after a DNA test. The honest answer is more interesting than yes or no. Ancient DNA has shown that the Vikings weren't a single people at all.
In short
- The Viking Age ran from about 750 to 1050 CE, when Scandinavians raided, traded and settled from Newfoundland to the Caspian Sea.
- DNA from 442 Viking Age skeletons shows "Viking" was a way of life, not a gene pool. Some people buried as Vikings had no Scandinavian ancestry at all.
- Danish, Swedish and Norwegian Vikings mostly went to different places, and each left a different genetic trace.
- Many people with British, Irish or Scandinavian roots carry some ancestry from Viking Age Scandinavians.
Who were the Vikings?
Strictly speaking, "Viking" described an activity: going viking meant sailing off to raid or trade. Most Scandinavians of the time were farmers and fishers living in long timber houses. But from the late 700s, fleets of fast, shallow-draft longships began crossing the North Sea.
The raid on the monastery at Lindisfarne in 793 CE is usually taken as the start of the Viking Age. Raiding grew into conquest. In 865 the Great Army landed in England and carved out the Danelaw. Viking Dublin was founded in 841. In 911 a Frankish king granted land to a Norse leader, the beginning of Normandy. Later, King Cnut ruled England, Denmark and Norway together.
Where the Vikings went
- West, across the Atlantic: Norse settlers reached Iceland around 870 and Greenland around 985. At L'Anse aux Meadows in Newfoundland, wood cut with metal tools has been dated to 1021 CE, making the Norse the first known Europeans in North America.
- East, down the rivers: Scandinavians known as the Rus', mostly from Sweden, traded down the rivers of Russia and Ukraine to Constantinople and the Caspian. They helped found Kyivan Rus', and some served Byzantine emperors in the elite Varangian Guard. Hoards of Islamic silver coins in Scandinavia come from this trade.
- South and west: England, Scotland's islands, Ireland, the Isle of Man and Normandy all saw lasting Norse settlement.
What DNA revealed: "Viking" wasn't a bloodline
In 2020 a team sequenced 442 people from Viking Age sites across Europe and beyond, the largest study of its kind. Three findings changed the picture:
- Different Vikings went to different places. Ancestry most like today's Danes spread mainly into England. Ancestry most like today's Swedes went east into the Baltic. Ancestry most like today's Norwegians went to Ireland, Scotland, Iceland and Greenland. That matches the history: the Danelaw was Danish, the Rus' were largely Swedish, and the Atlantic settlements were largely Norwegian.
- You didn't need Scandinavian DNA to be a Viking. Two men buried with Viking swords and full Viking rites in Orkney were genetically similar to today's Irish and Scots. Being a Viking was about culture, allegiance and way of life.
- Scandinavia was a mixing ground too. During the Viking Age, Scandinavia itself received new ancestry from elsewhere in Europe, through trade, marriage and the movement of enslaved people.
How the Vikings blended in
Wherever they settled, the Norse eventually blended into local populations. In Normandy, within a few generations, the descendants of Norse settlers spoke French and were Christian. Their descendants, the Normans, went on to conquer England in 1066. In Russia, the Rus' elite adopted the Slavic language. In England, the Danelaw left hundreds of place names ending in -by and -thorpe, and everyday words like sky, egg, window and they. In Iceland and the Faroes, Old Norse lives on almost unchanged.
The genetic trace followed the same pattern. It became part of the local mix rather than staying separate, which is why Viking ancestry shows up as a share of many people's DNA rather than as a distinct group.
Do you have Viking DNA?
If your family comes from Scandinavia, almost certainly, since today's Scandinavians descend largely from Viking Age Scandinavians. For people with roots elsewhere:
- Iceland: a large share of Icelandic ancestry is Norse, and most of the rest is Gaelic, from Ireland and Scotland. Studies suggest many of the settlers' wives came from the British Isles.
- Britain and Ireland: many people carry some Viking Age Scandinavian ancestry. It's usually a modest share, and higher in Orkney, Shetland and parts of northern and eastern England.
- Elsewhere: Normandy, the Baltic and parts of Eastern Europe have smaller traces.
A reality check on test results: a "Scandinavian" percentage on AncestryDNA or MyHeritage doesn't prove Viking ancestry. It means part of your DNA resembles people in Scandinavia today, and that ancestry could come from before, during or after the Viking Age. Europe's populations are closely related, so small percentages can also be statistical noise.
Some tests do give clues. Certain paternal lineages (Y-DNA haplogroups, especially branches of I1 and parts of R1a and R1b) are common in Scandinavia and are often found in Viking Age graves. FamilyTreeDNA's Y-DNA tests go deep enough to place your paternal line on a specific branch.

No test can prove a Viking ancestor, but each of these answers a different part of the question:
- AncestryDNA has the largest database and splits Scandinavian ancestry into regions, which helps if you want to know whether your roots lean Norwegian, Swedish or Danish. It's also the best for finding living relatives who can extend your family tree back toward Scandinavia.
- MyHeritage DNA has a strong European customer base, so it's good for matching with relatives still living in Scandinavia and northern Europe.
- A Y-DNA test from FamilyTreeDNA (for people with a Y chromosome) traces one line, your father's father's, deep enough to place it on a specific branch. If that branch turns up in Viking Age graves, that's about as direct a Viking link as DNA can give.

Frequently asked questions
Were the Vikings blond and tall?
Ancient DNA suggests blond hair was common, especially in Scandinavia, but far from universal. Many Viking Age people had brown hair. Their height was similar to other Europeans of the time.
Which DNA test shows Viking ancestry?
No consumer test can confirm a Viking ancestor. AncestryDNA and MyHeritage show modern Scandinavian-like ancestry. 23andMe and FamilyTreeDNA report haplogroups, which can point to lineages common among Viking Age Scandinavians. See our best DNA test picks.
Are the Normans descended from Vikings?
Partly. Normandy was founded by Norse settlers in 911, but they were few compared with the local Frankish population, and their descendants blended in within a few generations.
Were the Vikings one people?
No. They came from what are now Denmark, Norway and Sweden, spoke dialects of Old Norse, and sometimes fought each other. DNA shows they mixed with many other peoples too.
