Denali is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. It is the tallest mountain in the world from base-to-peak on land, measuring 18,000 ft (5,500 m), and Earth's highest mountain north of 43°N. With a topographic prominence of 20,194 feet (6,155 m) and a topographic isolation of 4,621.1 miles (7,436.9 km), Denali is the third most prominent and third-most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve.

A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.
