Porenut (Latin: Porenutius, Poremicius[1]) is a god with unknown functions mentioned in only two sources: Gesta Danorum and in Knýtlinga saga.

Saxo describes that in this gord (stronghold) there were three temples dedicated to Rugiaevit, Porevit and Porenut.

After the destruction of the temple and the ideol of Rugiaevit by the Danes, Saxo writes:[2][3] And not satisfied with its destruction, a group of auxiliary troops turned greedily to the statue of Porevit, which was worshiped in the temple next door.

[4] The same information is then given by the Knýtlinga saga, which lists Porenut in the distorted form Turupit (Old Icelandic: Turupið).

[10] Andrzej Szyjewski is also in favor of combining the first part of both Porevit and Porenut with the word pora.
