Landvættir

thumb|right|Four beings commonly identified as landvættir, as described in the Heimskringla version of [[Óláfs saga Tryggvasonar, as supporters on the coat of arms of Iceland.]] Landvættir ("land spirits" or "land wights") are spirits of the land in Old Nordic religion, later folk belief and modern Heathenry. They are closely associated with specific locations and their wellbeing is presented as being required for the land they inhabit to be fruitful. In Old Norse sources, they are depicted as being potentially harmful and capable of driving away unwanted individuals and capable of being frightened through human actions such as usage of carved figureheads on ships or níðstangs. Good relationships between humans and landvættir were believed to be fostered through acts like leaving out food for them. However upon the establishment of the church, the practice was labelled heretical and explicitly forbidden in the Norwegian Gulating law codes.

Landvættir have been variously connected by scholars to other beings believed to inhabit the land such as elves, dwarfs and landdísir, with which they were potentially identified at different points in history. Their belief and veneration has been revived in the modern period as part of the practice of modern Heathens.
