List of mountains in Ireland

This is a list of mountains and mountain ranges in Ireland. It also includes landforms that are usually called hills. Those within Northern Ireland or on the border are marked with an asterisk (*), while the rest are within the Republic of Ireland. Mountain ranges are in bold.

Thirteen peaks are classified by the Scottish Mountaineering Club as Furths i.e. mountains over 3,000 feet (910 m) in the British Isles outside Scotland that are regarded as separate mountains. Ten of these are located in Macgillycuddy's Reeks in County Kerry.

Mountains, in both Great Britain and Ireland, are commonly defined as any summit at least 2,000 feet (610 m) high. In addition, some definitions also include a topographical prominence requirement, typically 100 feet (30 m) or 500 feet (150 m).

A number of lists are maintained by the Mountainviews.ie online Hillwalking community, using criteria developed by that community and others. These include; the Valdeleur-Lynams, a list of 269 mountains being of at least 600 m (2,000 ft) in height with a prominence of at least 15 m (50 ft), and the Arderins; a list of 404 mountains of at least 500 m (1,600 ft) in height with a prominence of at least 30 m (100 ft). These lists have been published in book form by Collins Press. Mountainviews.ie classifies a mountain as being above 500 m (1,600 ft), but also maintains a number of lists of hills below this threshold.
