Þórisvatn (; sometimes anglicized to Thorisvatn) is the largest lake of Iceland, situated at the south end of the Sprengisandur plateau within the highlands of Iceland.

It is a reservoir with a surface area of about and is fed by the river Þjórsá, which comes down from the glacier Hofsjökull. On its southern end, Þórisvatn is used to generate electricity at a power station. It is like other Icelandic lakes, which are mostly glacial lakes or volcanic lakes.

The lake grew from about 70 km<sup>2</sup> to 86 km<sup>2</sup> with the construction of the power station and was previously only the second largest lake in the country.
