Antarctica is the coldest place on Earth. It is a frozen desert with little precipitation; the South Pole itself receives almost none. Temperatures reach a minimum of between -85 °C and -90 °C (-121 °F and -130 °F) in the winter and about 20 °C (30 °F) higher in the summer months. Sunburn is often a health issue as the snow surface reflects over 90% of the sunlight falling on it.[22] Eastern Antarctica is colder than its western counterpart because of higher elevation. Weather fronts rarely penetrate far into the continent, leaving the center cold and dry. Despite the lack of precipitation over the central portion of the continent, ice there lasts for extended time periods. Heavy snowfalls are not uncommon on the coastal portion of the continent, where snowfalls of up to 1.22 meters (48 inches) in 48 hours have been recorded.
Mountain glaciation.At the edge of the continent, strong katabatic winds off the polar plateau often blow at storm force. In the interior, however, wind speeds are typically moderate. During summer more solar radiation reaches the surface at the South Pole than is received at the equator in an equivalent period.[23]
Antarctica is colder than the Arctic for two reasons. First, much of the continent is more than 3 km above sea level, and temperature decreases with elevation. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica.
Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world. The aurora australis, commonly known as the southern lights, is a glow observed in the night sky near the South Pole. Another unique spectacle is diamond dust, a ground-level cloud composed of tiny ice crystals. It generally forms under otherwise clear or nearly clear skies, so people sometimes also refer to it as clear-sky precipitation. A sun dog, a frequent atmospheric optical phenomenon, is a bright "spot" beside the true sun.[22]

My ex-wife's heart. . .
The others have it right it is Antarctica.
The lowest temperature ever recorded on earth was -129F recorded in 1983 at the Russian Base Vostok in Antarctica. Antarctica, a continent owned by no one, covers the southern end of our globe. In addition to being the coldest place on earth, Anarctica is also the wettest and the driest place on earth. How is this possible?
70% of the worlds fresh water is in the ice sheets of Antarctica, that makes it pretty wet.
Antarctica is technically a dessert. It receives less than two inches of precipitation a year, about the same amount of precipitation as the Sahara Desert.

Antarctica, particularly South Pole and Vostok 2.
If you look at only the Northern Hemisphere, Verkhoyansk and Oymaykon in Siberia are the coldest.
