Vikings TV Show Names: What They Mean and Who Was Real

By , Norse Name Generator

Short answer: The first name in Ragnar Lothbrok is a two-part Old Norse name that two sources read as “counsel” plus “army,” and Lothbrok is a nickname. The man is legendary, and the show mixes real people like Rollo and Ivar with saga heroes like Lagertha and invented ones like Athelstan.

A guide for fans of the TV series: what the main names mean and which characters were real, legendary or invented.

I wrote this guide and read every source linked at the end of it on November 1, 2026. Name meanings are the weakest part of this topic: the dictionary-style pages for these names were out of reach, so Ragnar and Ivar each rest on two general-interest or community sources, and for Floki and Lagertha I report what the sources say or do not say instead of guessing. Who was real comes mainly from World History Encyclopedia. This site is not affiliated with the TV series. Page last updated November 1, 2026.

What does Ragnar mean?

Ragnar is the Old Norse name Ragnarr. Looper, citing the Name Doctor site, says it combines ragin-, “counsel,” and hari, “army.” Like most Old Norse names it is a two-part compound, which the names and meanings guide explains. Wiktionary gives the same reading, tracing Ragnarr to regin or rǫgn, “counsel,” and herr, “army.” Neither is a scholarly name dictionary, so treat it as a best reading.

The man behind the name is a harder question. World History Encyclopedia says Ragnar “may never have existed or, if he did, not as he is presented in the series.” His main literary source is the 13th-century Saga of Ragnar Lothbrok, and scholars generally think the legend was probably based on Reginherus, a 9th-century leader known for the 845 siege of Paris.

What does Lothbrok mean?

Lothbrok is a nickname, not a surname. It comes from loðbrók, “shaggy trousers,” and World History Encyclopedia gives it as “Hairy-breeches” or “Shaggy-breeches.” The story attached to it says he wore shaggy garments when he fought a giant serpent (Aberdeen, Mental Floss). The University of Aberdeen item points out that the TV series left the nickname unexplored and used it almost like a surname.

A real Norse naming pattern would have been a patronymic plus a nickname. The Aberdeen item’s own example of the pattern is Ragnarr Sigurðsson. Our Viking last names guide covers how that worked, and the nicknames guide has more bynames like this one.

Which characters in Vikings were real?

The show mixes three kinds of people: real historical figures, saga heroes who may never have lived, and characters invented for television. The table follows World History Encyclopedia, with extra detail from Looper where noted.

Floki: a real name from the sagas

The real Flóki

The real Flóki Vilgerðarson appears in Landnámabók, the Book of Settlements. The Environment Agency of Iceland says he is described as a great Viking from Norway, and that he took three ravens on his voyage and released them to find land. He was later called Hrafna-Flóki after the ravens (Environment Agency of Iceland, Fun Iceland). Hrafn is the Old Norse word for raven, as in the surname Raven in our last names guide.

Iceland and what came after

From a mountain above Vatnsfjörður he saw a fjord full of pack ice and named the country Iceland. If the Landnáma account is true, he was there around 860 to 870. His family lost their livestock to poor winter feed, they returned to Norway, and he later resettled in Skagafjörður, where he died (Environment Agency of Iceland, Fun Iceland).

How sources rank him, and the name itself

Sources disagree on how to rank him. One calls him the first Nordic man to spend a winter in Iceland, another the second Norwegian to reach it after Garðar Svavarsson told him of the island, and Looper says he did not discover it. The Old Norse Dictionary lists flóki as a word meaning “flock,” felt, hair or wool, and also a kind of halibut, and it lists Flóki as a personal name in Landnámabók. It does not say the name comes from any of those words, so I will not guess.

Lagertha: a name with several possible readings

Lagertha appears only in Saxo Grammaticus’s Gesta Danorum, a Latin work from the early 13th century. World History Encyclopedia says the first nine books of that work, where her story sits, are believed to be largely fictional. Saxo’s spelling is Ladgerda, and the Old Norse form is Hlaðgerðr (World History Encyclopedia, Looper). The other encyclopedia article used here ties her to the Saga of Ragnar Lothbrok instead, so sources differ on where she first appears.

Nobody agrees on what the name means. The encyclopedia suggests it may come from Hlað(a)-Gerðr, linked to Hlaðir (Lade), where the jarl Hákon lived, and says gerðr is a giant-daughter in Norse myth and the word is said to mean “embrace.” Viking Answer Lady says the -gerðr ending in women’s names probably relates to garðr, “fence, defense.” Looper calls the most common theory that Saxo’s Lagertha shifted from Lathgertha, another name for the goddess Thorgerd. That is three readings and no settled answer. See the female name generator for names with firmer roots.

Ivar, Björn and the nicknames

What Ivar means

Ivar is Ívarr. Looper says the name is believed to combine ýr, “bow” or “archer,” with hariar, “warrior,” roughly “archer warrior,” and notes ýr can also mean yew tree. Wikipedia says the name has several possible etymologies: the first element may contain ýr, “yew,” and the second is most likely -arr, from hari, “warrior.” Wiktionary traces it to Proto-Germanic words glossed “yew tree, bow” and “warrior, army.” The three agree on yew or bow plus warrior, but none is a scholarly name dictionary.

Why “Boneless”?

The nickname “Boneless” has no settled explanation either. Looper lists a bone condition, a metaphor for a snake-like cunning (from Robert Ferguson’s The Hammer and the Cross), and a possible mistranslation of the Latin exosus, “detested.” It says there is no consensus.

Björn and Kjetill

Björn is simpler. Bjǫrn means “bear,” and Viking Answer Lady records it as a name element in names like Abjǫrn (Viking Answer Lady). Harald Finehair’s real nickname has its own history in our nicknames guide, where Medievalists.net says it started as lúfa, “shock head.” The show also has a Kjetill Flatnose among its Iceland settlers (Looper). Ketil Flat-Nose, flatnefr, is a recorded nickname, and Viking Answer Lady names Ketill flatnefr as the father of Auðr the Deep-Minded.

Using show names for your own character

  1. Real, recorded names work best. Björn and Ívarr are both real Old Norse names. The male name generator and female name generator build names from real elements.
  2. Treat show-style epithets as nicknames, not surnames. If you want a Lothbrok-style label, build it like a byname, and give the character a patronymic for the last name. The trait surname generator makes hyphenated nicknames.
  3. Know which names are legend. Ragnar, Björn Ironside and Lagertha come from saga material, which is fine for fiction, but they are not records of real people.

Frequently asked questions

What does Ragnar mean?

Looper, citing the Name Doctor site, says Ragnar combines ragin-, meaning counsel, and hari, meaning army. Wiktionary gives the same reading, from regin or rǫgn and herr. Neither is a scholarly name dictionary, so treat it as a best reading.

Was Ragnar Lothbrok a real person?

Probably not as shown. World History Encyclopedia says he may never have existed or, if he did, not as the series presents him. Scholars generally think the legend was probably based on Reginherus, a 9th-century leader known for the 845 siege of Paris.

Was Floki a real Viking?

The name belongs to a real man, Flóki Vilgerðarson, who appears in Landnámabók and is tied to the naming of Iceland. World History Encyclopedia says the show’s Floki is almost wholly fictionalized.

Was Lagertha real?

She appears only in Saxo Grammaticus’s Gesta Danorum, and World History Encyclopedia says the first nine books of that work, where her story sits, are believed to be largely fictional. Looper says there remain doubts about whether she was a real person.

Which characters in Vikings were real?

Rollo, Ivar the Boneless, King Ecbert of Wessex and Harald Finehair correspond to real people, with changes. Ragnar, Björn Ironside and Lagertha come from legend, Floki is based on a real man, and Athelstan was invented for the show.
