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 2,000 feet (609.6 m) in height, the general requirement to be called a "mountain" in the British Isles, and over 100 feet (30.5 m) in prominence, and which also had "sufficient topographical merit" that he outlined in a complex formula.

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.

"[3][2] 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.

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:[13][14]
