The Norse gods are one extended, often quarrelsome family. At the top sits Odin, the Allfather, whose children include Thor and Baldr, while Loki—though not Odin’s blood son—is his sworn blood-brother and the father of several monsters. This article maps the main divine family lines as told in the Poetic Edda and the Prose Edda, the two main sources for Norse mythology.
Who Is the Head of the Norse Pantheon?
Odin is the chief of the Aesir, the principal group of Norse gods. He is the god of wisdom, war, poetry, and the dead, and he rules from Asgard. According to the Prose Edda, Odin is the son of Borr and the giantess Bestla, making him half-giant. His brothers are Vili and Vé, with whom he helped shape the world from the body of the giant Ymir.
Odin is married to Frigg, the goddess of marriage and foresight. Their children include Baldr, the beloved and beautiful god, and Hodr, the blind god who accidentally kills Baldr. Odin is also the father of Thor, but not with Frigg—Thor’s mother is Jord, a giantess who is also personified as the Earth.
Odin’s Children: The Main Aesir Line
Odin’s offspring appear throughout the myths, and their mothers vary. Here are the most prominent:
- Thor – god of thunder, strength, and protection. His mother is Jord, and his wife is Sif.
- Baldr – god of light and purity, killed by a mistletoe spear at Loki’s instigation.
- Hodr – blind god who throws the mistletoe spear that kills Baldr.
- Vidar – god of vengeance, who kills Fenrir at Ragnarok. His mother is the giantess Grid.
- Vali – born to avenge Baldr’s death; his mother is the giantess Rind.
Odin also has a daughter, the valkyrie Brynhildr, in the Völsunga saga, though her divine status is debated. In the Poetic Edda, she is a valkyrie and a human princess, not clearly a goddess.
Thor’s Family and Offspring
Thor is married to Sif, a goddess associated with grain and fertility. Their children are Thrud, a strong goddess, and Modi and Magni, who survive Ragnarok. Thor also has a son, Ullr, with Sif, though some sources say Ullr is Sif’s son from an earlier marriage. Ullr is the god of skiing, hunting, and dueling.
Thor’s most famous enemy is the Midgard Serpent, Jormungandr, who is actually his own half-brother (see Loki’s family below). At Ragnarok, Thor kills the serpent but dies from its venom.
Loki and His Monstrous Children
Loki is a giant by birth, but he lives among the Aesir and becomes Odin’s blood-brother. His family is central to many myths:
- With the giantess Angrboda, Loki fathers Fenrir the wolf, Jormungandr the world serpent, and Hel, the ruler of the underworld.
- With his wife Sigyn, Loki has two sons, Narfi and Vali (not to be confused with Odin’s son Vali). In one version, Narfi is killed and his entrails are used to bind Loki.
- Loki also gives birth to Sleipnir, Odin’s eight-legged horse, after turning into a mare and mating with the stallion Svadilfari.
These children are not just monsters—they are prophesied to fight against the gods at Ragnarok. Fenrir will kill Odin, and Jormungandr will fight Thor.
Other Major Families: Njord, Frey, and Freyja
The Vanir are a second group of gods associated with fertility, wealth, and peace. After a war between the Aesir and Vanir, they exchanged hostages. Njord and his children Frey and Freyja came to live in Asgard.
- Njord – god of the sea and winds. His wife is Skadi, a giantess, but their marriage fails because they cannot agree on where to live.
- Frey – god of fertility, peace, and good harvest. He owns the ship Skidbladnir and the boar Gullinbursti. He falls in love with the giantess Gerd, and their son is Fjolnir (in some sagas).
- Freyja – goddess of love, beauty, and war. She leads the valkyries and takes half of the slain warriors to her hall, Folkvangr. She is the daughter of Njord and the sister of Frey.
Freyja’s husband is Odr, who is often absent, and she weeps golden tears for him. Their daughter is Hnoss, whose name means ‘treasure’.
How the Family Tree Works (and Where It Gets Messy)
Norse mythology does not have a single, consistent family tree. Different poems and sagas give different parents for the same god. For example, in the Prose Edda, Odin is the son of Borr and Bestla, but in the Poetic Edda’s Lokasenna, Loki says Odin once sent him into the underworld, implying a different relationship.
The main complication is that the gods are not purely divine—they often marry or have children with giants. This makes the family tree a mix of Aesir, Vanir, and giant lineages. Also, some gods are adopted or become blood-brothers, like Loki, which adds another layer.
Another issue is that the sources were written down by Christians in the 13th century, long after the Viking Age. The Prose Edda by Snorri Sturluson is the most systematic, but it may have been influenced by Christian ideas. The Poetic Edda is older and more fragmentary.
Common Misconceptions About the Norse Gods
One common mistake is thinking that Loki is a god. In the sources, he is a giant who lives among the gods, and he is never called a god. Another misconception is that there are only two groups of gods, Aesir and Vanir, but there are also other divine beings like the valkyries and the norns.
People also assume that the Norse gods are immortal, but they can be killed. Baldr dies, and at Ragnarok, many gods die, including Odin, Thor, and Frey. The gods are powerful but not all-knowing or all-powerful.
Finally, the family tree is not a simple pyramid. It is a web of relationships, with many connections between gods and giants. For example, Thor’s mother is a giantess, and his daughter Thrud is the subject of a poem where the dwarf Alvis tries to marry her.
Frequently Asked Questions
Who is Odin’s wife?
Odin’s wife is Frigg, the goddess of marriage and motherhood. She is the only goddess who is his equal in status, and she is the mother of Baldr and Hodr. In some stories, she also has a hand in the fates of heroes.
Are Thor and Loki brothers?
No, they are not brothers in the myths. Loki is Odin’s blood-brother, which makes him an uncle to Thor in a ceremonial sense. In the Marvel comics and movies, they are portrayed as brothers, but that is a modern invention.
Who is the mother of Sleipnir?
Sleipnir, Odin’s eight-legged horse, is born from Loki, who transformed into a mare and was impregnated by the stallion Svadilfari. So Loki is the mother, not the father, of Sleipnir.
What are the names of the three Norns?
The three Norns are Urd (past), Verdandi (present), and Skuld (future). They live at the base of Yggdrasil, the world tree, and they spin the threads of fate for all beings, gods included.
Is Freya the same as Frigg?
No, they are separate goddesses. Freya is a Vanir goddess of love and war, while Frigg is an Aesir goddess of marriage. Some scholars think they may have originated from the same deity, but in the surviving sources, they are distinct.
Who survives Ragnarok?
After Ragnarok, the world is reborn, and several gods survive, including Thor’s sons Modi and Magni, Odin’s son Vidar and Vali, and Baldr and Hodr, who return from the dead. The humans Lif and Lifthrasir also survive to repopulate the earth.
