Laurasia was a supercontinent. It had been the northern part of the Pangaea global supercontinent. Pangaea split into Laurasia and Gondwana to the south during the Jurassic period.

Laurasia included most of the landmasses which make up today's continents of the northern hemisphere, chiefly Laurentia (the name given to the North American craton), Europe, Scandinavia, western Russia, Siberia, Kazakhstan, and China.

Laurasia's name combines the names of Laurentia and Eurasia.
