In Norse mythology, Narfi or Nörfi (Nǫrfi), also called Nörr (Nǫrr), is the father of Nótt, the personified night.
According to the Gylfaginning section of Snorri Sturluson's Prose Edda, Nótt is the daughter of the jötunn "Nörfi or Narfi". However, in the Poetic Edda, Nótt's father is called Nörr (not to be confused with Nór), primarily for reasons of alliteration. This name is only recorded in the dative form Nǫrvi (variant spelling Naurvi).
The name of Nótt's father is recorded in several forms in Old Norse sources:
The form Nörr has been related to narouua, which occurs in the fragmentary Old Saxon Genesis poem in the phrase narouua naht. This and hence the giant's name, as first suggested by Adolf Noreen, may be a synonym for "night" or, perhaps more likely, an adjective related to Old English nearwe, "narrow", meaning "closed-in" and thus "oppressive".
Various scholars have argued that Snorri based his genealogy of Nótt on classical models. They relate Narfi to Erebus, which would make nipt Nera, used in "Helgakviða Hundingsbana I" for a Norn who comes in the night, an appellation derived from the Parcae, who were Erebus' daughters.
In "A Great Man's Return", a song on their album Valdr Galga, the Swedish viking metal band Thyrfing refer to "Norve's starfilled sky".
