Lists of mountains and hills in the British Isles

The mountains and hills of Great Britain, and to a lesser extent Ireland, are the subject of a considerable number of lists that categorise them by height, topographic prominence, or other criteria. They are commonly used as a basis for peak bagging, whereby hillwalkers attempt to reach all the summits on a given list. The oldest and best known of these lists is that of the Munros, mountains in Scotland over 3,000 feet (914 m); other well-known lists include the Corbetts, Wainwrights and Marilyns.

There is no worldwide consensus on the definition of "mountain", but in Great Britain and Ireland it is often taken to be any summit at least 2,000 feet (or 610 metres) high. The UK government defines mountain as land over 600 metres for the purposes of freedom of access. In addition, some definitions also include a topographical prominence requirement, typically 100 feet (30 m) or 500 feet (152 m). In practice, mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as the Cuillin Hills and the Torridon Hills. In Wales, the distinction is more a term of land use and appearance which has nothing to do with height.
