In Norse mythology, Vár or Vór (Old Norse, meaning either "pledge" or "beloved") is a goddess associated with oaths and agreements. Vár is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda, written in the 13th century by Snorri Sturluson; and kennings found in skaldic poetry and a runic inscription. Scholars have proposed theories about the implications of the goddess.

In the Poetic Edda poem Þrymskviða, the blessed of Vár is invoked by the jötunn Þrymr after his "bride" (who is actually the god Thor disguised as the goddess Freyja) is hallowed with the stolen hammer of Thor, Mjöllnir, at their wedding:

In the chapter 35 of the Prose Edda book Gylfaginning, High tells Gangleri (described as king Gylfi in disguise) about the ásynjur. High lists Vár ninth among the sixteen ásynjur he presents in the chapter and provides some information about her:

Ninth Var: she listens to people's oaths and private agreements that women and men make between each other. Thus these contracts are called varar. She also punishes those who break them.
