Corrieshalloch Gorge (Scottish Gaelic: Coire Shalach, meaning unattractive corrie) is a gorge situated about south of Ullapool, close to the junction of the A832 and A835 roads near Braemore in the Scottish Highlands. The gorge is approximately long, deep, and wide at its lip. The Abhainn Droma flows through Corrieshalloch, below which the landscape opens out into a broad, flat-bottomed glacial trough at the head of Loch Broom.) can be viewed from a viewing platform and a Victorian suspension footbridge. The gorge has been owned since 1945 by the National Trust for Scotland who manage it and the surrounding area jointly with NatureScot. Access to the footbridge is via a long path from the car park on the south side of the gorge. There is a charge of £2 payable for parking using an honesty box at the start of the path. A viewing platform has been installed which projects out into the gorge.

In December 2019, a £2.3 million investment in upgraded parking and a visitor centre was announced. The centre opened in 2023.
Nature and conservation
The gorge provides a habitat for plants that have largely disappeared from the surrounding areas due to grazing pressures. The dark, humid walls of the gorge support ferns, feather mosses and sanicle; wood millet, a plant otherwise rare in northwest Scotland. Higher up, the more sunlit slopes support trees such as wych elm, birch, sycamore, Norway maple and beech.
The wooded parts of the gorge support a population of the cranefly species Lipsothrix ecucullata, which is nationally rare. The larvae of this species inhabit wet, decayed wood, whilst the mature adults inhabit damp deciduous woodlands.
Corrieshalloch Gorge is a national nature reserve (NNR) and a Site of Special Scientific Interest (SSSI), and is classified as a Category III protected area by the International Union for Conservation of Nature. It is the smallest of Scotland's 43 national nature reserves.
The gorge is suffering small-scale invasion by aggressive alien plant species (rhododendron and Japanese knotweed), and specialist access to the gorge walls and floor is being deployed to control it.
