The frigid zone is a geographical zone that is found near the polar regions of planet Earth. The northernmost parts of North America and Europe are located in the frigid zone, as are Greenland, half of Iceland, and the whole continent of Antarctica. There are no areas belonging to the frigid zone in South America.

The frigid zone experiences an extremely cold winter every year. The northernmost parts of the region have no summer. Snow rarely has time to melt completely during the summer. The monthly average temperature never rises above 10 degrees Celsius.
