迪纳利峰或迪纳利山（北阿萨巴斯卡语支、英语：Denali，直译“高山”），1917年至2015年官方名称为麦金利山（另译作麦金利峰，英文：Mount McKinley），位于阿拉斯加州东南部、阿拉斯加山脉中段，海拔6194米，是北美洲最高峰，也是美国的最高峰。它的俄语名称是Большая Гора（转写：Bolshaya Gora），意思是“大山”。

迪纳利山地区拥有变幻莫测的高山风、典型的北极植被以及野生动植物。这里大部分地区终年积雪，山间经常浓雾不断，雾气在皑皑白雪中缭绕弥漫时，几百米之外的景物便不可见。夏季，迪纳利山的青青山坡上鲜花盛开，紫色的杜鹃和精巧的铃状石南花随处可见。迪纳利山还是世界登山爱好者的汇集之地。每年5月到7月有数百人登山，只有一半不到的人能登顶成功。一次登山约花3个星期。

Denali /dᵻˈnɑːli/ (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. At some 18,000 ft (5,500 m), the base-to-peak rise is the largest of any mountain situated entirely above sea level. With a topographic prominence of 20,156 feet (6,144 m) and a topographic isolation of 4,629 miles (7,450 km), Denali is the third most prominent and third most isolated peak 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.
