This page tabulates only the most prominent mountains of the Alps, selected for having a topographic prominence of at least 300 metres (980 ft), and all of them exceeding 3,000 metres (9,800 ft) in height. Although the list contains 537 summits, some significant alpine mountains are necessarily excluded for failing to meet the stringent prominence criterion. The list of these most prominent mountains is continued down to 2500 m elevation at List of prominent mountains of the Alps (2500–2999 m) and down to 2000 m elevation on List of prominent mountains of the Alps (2000–2499 m). All such mountains are located in either France, Italy, Switzerland, Liechtenstein, Austria, Germany or Slovenia, even in some lower regions. Together, these three lists include all 44 ultra-prominent peaks of the Alps, with 19 ultras over 3000m on this page. For a definitive list of all 82 the highest peaks of the Alps, as identified by the International Climbing and Mountaineering Federation (UIAA), and often referred to as the 'Alpine four-thousanders', see List of mountains of the Alps over 4000 metres.
