Skidbladnir (also spelled Skidbladner), in Norse mythology, a magic ship made by dwarfs and owned by Freyr, the god of fruitfulness and good weather. Skidbladnir was so large that it could hold on board all the Aesir gods with all their weapons, arms, and horses. Yet it had been so cleverly constructed by the dwarfs that when it docked and was no longer needed, it could be folded up like a handkerchief and carried across land in a small pouch. As soon as its sails were hoisted, Skidbladnir would go straight to its destination, and it could sail on air as well as on water. The ship was made by the sons of Ivald, the dwarfs of the forge, at the instigation of the trickster fire god Loki.
