This is the MountainViews 100 Highest Irish Mountains list, which was published by Collins Press in the 2013 book: A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins. It combines Paul Tempan's 2012 research into Irish mountains and Irish mountain names. The list requires a prominence of over , a compromise between the popular British Isles Marilyn criteria of 150 metres (see List of Marilyns in the British Isles for a ranking of Irish Marilyns by height and by prominence), and the Simms-Hewitt-Arderins criteria of 30 metres (see List of mountains of the British Isles by height for a ranking of Irish Simms by height and by prominence). It is a widely used list, and it contains 25 of the 26 Irish P600s (Slieve Snaght, a P600, did not make the 100 Highest).
