This is a list of Murdo mountains in Scotland by height. Murdos are defined as Scottish mountains over 3,000 feet (914.4 m) in height, above the general threshold to be called a "mountain" in the British Isles, and with a prominence over 30 metres (98 ft);^[1] a mix of imperial and metric thresholds.^[2]

British Isles cartographer Alan Dawson, first compiled the list of Murdos in 1995 to provide an objective and quantitative alternative to the more qualitative Scottish Mountaineering Club ("SMC") definition of a Munro.^{[lower-alpha 1][3]} Unlike all other Scottish mountain and hill classifications, the SMC does not maintain an official list of Murdos.^[4] However, all Murdos are either SMC Munros or SMC Munro Tops.^[1] Dawson's threshold was in line with the 1994 UIAA declaration that an "independent peak" had to have a prominence of over 30 metres (98 ft).^[5]

As of October 2018^[update], there were 442 Murdos identified in Scotland.^[6] Most definitions of mountains in the British Isles consider peaks with a prominence between 30–150 metres (98–492 ft) as being "tops", and not mountains. 203 of the 442 Murdos exceed this 150 metres (492 ft) prominence threshold, and thus are marilyns.^[6] 54 of the 442 Murdos exceed the P600 prominence threshold of 600 metres (1,969 ft) to be a "major" mountain.^[6]

When Dawson created the Murdos in 1995 he said "all Munros are Murdos", and listed Maoile Lunndaidh, a Munro, with a prominence of 400 metres (1,312 ft).^[2] Surveys in 2014, showed Maoile Lunndaidh was lower than Creag Toll a' Choin,^[7] and its prominence was 11 metres (36 ft); 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.^{[8][lower-alpha 2]}

The list below was downloaded from the Database of British and Irish Hills ("DoBIH") as at October 2018.^{[10][lower-alpha 3]} 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.^[13] 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").

The DoBIH uses the following codes for the various classifications of mountains and hills in the British Isles, which many of the above peaks also fall into:^[14][15]
