A Munro (listen ) is defined as a mountain in Scotland with a height over 3,000 feet (914.4 m), and which is on the Scottish Mountaineering Club (SMC) official list of Munros; there is no explicit topographical prominence requirement. The best known Munro is Ben Nevis (Beinn Nibheis), the highest mountain in the British Isles at 4,411 ft (1,345 m).

Munros are named after Sir Hugh Munro, 4th Baronet (1856–1919), who produced the first list of such hills, known as Munro's Tables, in 1891. Also included were what Munro considered lesser peaks, now known as Munro Tops, which are also over 3,000 feet but are lower than the nearby primary mountain. The publication of the original list is usually considered to be the epoch event of modern peak bagging. The list has been the subject of subsequent variation and as of 10 December 2020, the Scottish Mountaineering Club has listed 282 Munros and 226 Munro Tops.

"Munro bagging" is the activity of climbing all the listed Munros. As of 31 December 2022, 7,390 people had reported completing a round. The first continuous round was completed by Hamish Brown in 1974, whilst the record for the fastest continuous round is currently held by Donnie Campbell, who completed a round in just under 32 days in September 2020. Furths are mountains in England, Wales or Ireland recognized by the SMC as meeting the Munro classification.
