Skíðblaðnir, sometimes anglicized as Skidbladnir or Skithblathnir, is the best of ships in Norse mythology. It is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and in the Prose Edda and Heimskringla, both written in the 13th century by Snorri Sturluson. All sources note that the ship is the finest of ships, and the Poetic Edda and Prose Edda attest that it is owned by the god Freyr, while the euhemerized account in Heimskringla attributes it to the magic of Odin. Both Heimskringla and the Prose Edda attribute to it the ability to be folded up—as cloth may be—into one's pocket when not needed.

Freyr, sometimes anglicized as Frey, is a widely attested god in Norse mythology, associated with kingship, fertility, peace, prosperity, fair weather, and good harvest. Freyr, sometimes referred to as Yngvi-Freyr, was especially associated with Sweden and seen as an ancestor of the Swedish royal house. According to Adam of Bremen, Freyr was associated with peace and pleasure, and was represented with a phallic statue in the Temple at Uppsala. According to Snorri Sturluson, Freyr was "the most renowned of the æsir", and was venerated for good harvest and peace.
