Carrauntoohil or Carrauntoohill is the highest mountain on the island of Ireland at 1,038.6 metres. It is on the Iveragh Peninsula in the Reeks District in County Kerry, close to the centre of Ireland's highest mountain range, MacGillycuddy's Reeks. Carrauntoohil is composed mainly of sandstone, whose glaciation produced distinctive features on the mountain such as the Eagle's Nest corrie and some deep gullies and sharp arêtes in its east and northeastern faces that are popular with rock and winter climbers.
In topography, prominence measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's key col is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
Slieve Croob is a mountain with a height of 534 metres (1,752 ft) in the middle of County Down, Northern Ireland. It is the heart of a mountainous area known as the Dromara Hills, north of the Mourne Mountains. It is designated an Area of Outstanding Natural Beauty and is the source of the River Lagan. There is a small road to the summit, where there is an ancient burial cairn and several transmitter stations with radio masts. It has wide views over all of County Down and further afield.

In these lists of mountains in Ireland, those within Northern Ireland, or on the Republic of Ireland – United Kingdom border, are marked with an asterisk, while the rest are within the Republic of Ireland. Where mountains are ranked by height, the definition of the topographical prominence used to classify the mountain, is noted. In British definitions, a height of 600 metres (1,969 ft) is required for a mountain, whereas in Ireland, a lower threshold of 500 metres (1,640 ft) is sometimes advocated.

The mountains and hills of the British Isles are categorised into various lists based on different combinations of elevation, prominence, and other criteria such as isolation. These lists are used for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list, the oldest being the 282 Munros in Scotland, created in 1891.
