Donald (hill)

This is a list of Donald mountains in Scotland by height. Donalds were defined in 1935 by Scottish Mountaineering Club ("SMC") member Percy Donald, as Scottish Lowlands mountains over in height, the general requirement to be called a "mountain" in the British Isles, and over in prominence, and which also had "sufficient topographical merit" that he outlined in a complex formula.

This formula splits Donalds into Donald Hills and Donald Tops. The SMC define Donald Tops as: "elevations in the Scottish Lowlands of at least 2000ft (610m) in height with a drop of at least 50ft (15.2m) between each elevation and any higher elevation. Further, elevations separated from higher elevations by a drop of less than 100ft (30.5m) are required to have "sufficient topographical merit". In addition, the SMC define Donald Hills as being: "defined from Donald Tops, where a Hill is the highest Top with a separation of 17 units or less. A unit is either one-twelfth of a mile along a Top's connecting ridge or 50ft (30.5m) in elevation between the Top and its connecting bealach/col. The separation is the sum of these two measures."

The SMC note that: "Percy Donald's original Tables are seen as a complete entity, unlike the Munros, Corbetts and Grahams"; thus many Donalds are also Corbetts or Grahams. Percy Donald's original 1935 list recorded 133 Donalds, however since 1997, the SMC records 140 Donalds in the Scottish lowlands, split into 89 Donald Hills and 51 Donald Tops. While the prominence of Donald Hills is over , the prominence of a Donald Top can range from , as in the case of Cairn Hill West Top, to , in the case of Beninner.

New Donalds were introduced by Alan Dawson in his 1995 book, ''The Grahams and the New Donalds'', with a prominence threshold of , and that the location was south of the Highland Boundary Fault; there are 118 New Donalds, and while all Donald Hills are New Donalds, 22 Donald Tops are not. Climbers who climb all SMC Donalds are called ''Donaldists'', the first being Percy Donald on 23 May 1933; a list is maintained.

Donald mountains by height

This list is from the ''Database of British and Irish Hills'' ("DoBIH") in October 2018, and are peaks the DoBIH marks as being Donalds ("D" and "DT"). The SMC does not update the list of Donalds (they are fixed), however the DoBIH also updates their measurements as more surveys are recorded, so these tables should not be amended or updated unless the entire DoBIH data is re-downloaded again.
