Lavvu (or , , , , , , and ) is a temporary dwelling used by the Sami people of northern Scandinavia. It has a design similar to a Native American tipi but is less vertical and more stable in high winds. It enables the indigenous cultures of the treeless plains of northern Scandinavia and the high arctic of Eurasia to follow their reindeer herds. It is still used as a temporary shelter by the Sami, and increasingly by other people for camping. It should not be confused with the goahti, an other type of Sami dwelling, or the Finnish laavu.
