Glen Coe (Scottish Gaelic: Gleann Comhann pronounced [klan̪ˠˈkʰo.ən̪ˠ]) is a glen of volcanic origins, in the Highlands of Scotland. It lies in the north of the county of Argyll, close to the border with the historic province of Lochaber, within the modern council area of Highland. Glen Coe is regarded as the home of Scottish mountaineering and is popular with hillwalkers and climbers.

A 2010 review by Scottish Natural Heritage into the special qualities of Scotland's National scenic areas listed the "soaring, dramatic splendour of Glen Coe", and "the suddenness of the transition between high mountain pass and the lightly wooded strath" as being of note. The review also described the journey through the glen on the main A82 road as "one of the classic Highland journeys". The main settlement is the village of Glencoe, located at the foot of the glen.

The Glen is named after the River Coe which runs through it. The name of the river may predate the Gaelic language, as its meaning is not known. It is possible that the name stems from an individual personal name, Comhan (genitive Comhain).

The glen is U-shaped, formed by an ice age glacier, about 12.5 kilometres (7+3⁄4 mi) long with the floor of the glen being less than 700 metres (3⁄8 mi) wide, narrowing sharply at the "Pass of Glen Coe".

The entrance to the glen from the east is below the foot of Buachaille Etive Beag just west of Lochan na Fola, from where waters run west to Loch Leven via the River Coe. The river — Ossian's "dark Cona" — passes over waterfalls at the Pass of Glen Coe before flowing down to the small Loch Achtriochtan. Loch Achtriochtan is Loch Trychardan (loch of the three friends or relatives) in Timothy Pont's map of the area. After the loch the river turns north-west, passing through Glencoe village, before flowing into the sea loch of Loch Leven (a salt-water arm of Loch Linnhe) at Invercoe. The area to the east of Lochan na Fola is often classed as part of Glen Coe (see for example the location of Glencoe ski centre), but is in fact part of the upper reaches of Glen Etive.

The south side of the glen is marked by a succession of distinct peaks: Buachaille Etive Beag at the eastern end, followed by the Three Sisters, shoulders of the Bidean nam Bian massif which are subdivided by Coire Gabhail and Coire nan Lochan. The name Coire Gabhail (corrie of the bounty, or hollow of capture) refers to former times when the corrie was used by members of Clan MacDonald to hide cattle and other livestock, whether their own or stolen from others. The wide flat glen is well suited for this purpose, since from Glen Coe it appears to be a normal V-shaped glen approached only by a steep narrow gorge. Summits in the Bidean nam Bian massif include Stob Coire Sgreamhach, Stob Coire nan Lochan and Aonach Dubh (the third "sister"). By contrast the north side of the glen is a stark wall of mountain, the Aonach Eagach ridge. The ridge is crossed at the eastern end by the Devil's Staircase, an old military road opposite Buachaille Etive Mòr. The western end terminates with the conical Pap of Glencoe (Sgùrr na Cìche), above Glencoe village, at the point where the glen opens out to Loch Leven.

Other than a few scattered farms, the only settlement in Glen Coe is the village of Glencoe, which lies at the western end of the glen close to Invercoe where the river joins Loch Leven. About 2 km (1.24 mi) to the west, on the southern shore of the loch, is the village of Ballachulish, known in the past for its slate quarries, which have been worked since 1693.

Geologically speaking, Glen Coe is the remains of an ancient supervolcano. The caldera forming eruptions took place about 420 million years ago during the Silurian period, and the volcano has long since become extinct. The glen is considered to be one of the best examples of a subsidence caldera, being the place where this phenomenon was first described. A caldera is a volcanic process in which a circular fault allows a section of crust to sink, leading to magma being forced to the surface at the periphery. This sinking allows layers of rock which would otherwise have been eroded to remain visible, and can be seen in Glen Coe most strikingly in Devonian volcanic lavas on Bidean nam Bian, as well as at Sgorr nam Fiannaidh, An t-Sron, and in the bed of the River Coe below Loch Achtriochtan. Surrounding the caldera the rocks consists of schist and quartzite with a ring of granite marking the main ring fault.

The landscape was further shaped by the processes of glaciation during the last ice ages, ending 10,000 years ago.
