List of Murdo mountains

This is a list of Murdo mountains in Scotland by height. Murdos are defined as Scottish mountains over 3,000 ft in height and with a prominence over 30 m; a mix of imperial and metric thresholds.

Cartographer Alan Dawson first compiled the list of Murdos in 1995 to provide an objective and quantitative alternative to the Scottish Mountaineering Club ("SMC") definition of a Munro, which has the same height threshold but a qualitative but a qualitative requirement of "sufficient separation", instead of prominence. The SMC does not maintain an official list of Murdos, unlike all its other Scottish mountain and hill classifications,. However, all Murdos are either SMC Munros or SMC Munro Tops. Dawson's threshold was in line with the 1994 International Climbing and Mountaineering Federation declaration that an "independent peak" had to have a prominence of over 30 m.

, there were 442 Murdos identified in Scotland. Most definitions of mountains in the British Isles consider peaks with a prominence between 30-150 m as being "tops", and not mountains. A total of 203 of the 442 Murdos exceed this 150 m prominence threshold, and thus are Marilyns. Of these, 54 exceed the P600 prominence threshold of 600 m to be a "major" mountain.

When Dawson created the Murdos in 1995 he said "all Munros are Murdos", and listed Maoile Lunndaidh, a Munro, with a prominence of 400 m. Surveys in 2014 showed Maoile Lunndaidh was lower than Creag Toll a' Choin, and its prominence was 11 m; databases of Murdos (e.g. the DoBIH), no longer list Maoile Lunndaidh as a Murdo (its prominence went to Creag Toll a' Choin), and thus not all Munros are Murdos.

Murdo mountains by height
The list below was downloaded from the Database of British and Irish Hills ("DoBIH") as at October 2018. Note that topological prominence, unlike topological elevation, is far more complex to measure and requires a survey of the entire contours of a peak, rather than a single point of height. These tables are therefore subject to being revised over time, and should not be amended or updated unless the entire DoBIH data is re–downloaded again. The DoBIH classification marks Munros ("M") and Munro Tops ("MT").
