Laurasia () was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around (Mya), the other being Gondwana. It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pangaea, drifting further north after the split and finally broke apart with the opening of the North Atlantic Ocean 56 Mya. The name is a portmanteau of Laurentia and Eurasia.
Laurasia was the northern half of the ancient supercontinent Pangaea, which began breaking away from the southern landmass Gondwana during the late Triassic period and eventually split apart around 56 million years ago as the North Atlantic Ocean opened up. It matters because understanding Laurasia helps explain how the continents we know today came to be positioned where they are and how the geography of our planet has changed over millions of years.

Laurentia, Avalonia, Baltica, and a series of smaller terranes, collided in the Caledonian orogeny c. 400 Mya to form Laurussia. Laurussia then collided with Gondwana to form Pangaea. Kazakhstania and Siberia were then added to Pangaea 290–300 Mya to form Laurasia. Laurasia finally became an independent continental mass when Pangaea broke up into Gondwana and Laurasia.
