The driest place on Earth is the Atacama Desert in Chile. This desert receives an average of less than 15 millimeters (0.6 inches) of rainfall per year, with some areas receiving virtually no rain at all.

It's important to note that "driest" can be defined in different ways. The Atacama is considered the driest in terms of average annual rainfall. However, other places might hold the record for longest periods without rain or lowest total rainfall ever recorded.
