<P> 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 . </P> <P> 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 . </P> <P> In Ireland, mountains 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). </P> <P> 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 about 270 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 about 400 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 . </P>
