Uppsala öd (Old Norse: Uppsala auðr or Uppsala øðr, meaning Uppsala domains or wealth of Uppsala) was the name given to the collection of estates which was the property of the Swedish Crown in medieval Sweden. Its purpose was to finance the Swedish king, originally the "king of Uppsala", and the income from these estates supported the king and his retinue while he travelled through the country. There was one estate of this kind in most hundreds and it was usually called Husaby.

Frey built a great temple at Upsal, made it his chief seat, and gave it all his taxes, his land, and goods. Then began the Upsal domains, which have remained ever since.

It was stated in the Swedish medieval laws that Uppsala öd was to follow the royal institution intact without any lost property.
