Ben Mor Coigach (Scottish Gaelic: Beinn Mhòr na Còigich) is the highest point along a ridge rising steeply from Loch Broom, in the far northwest of Scotland.

Its coastal position, combined with its high topographic prominence to height ratio, provides a spectacular panorama, sweeping from Ullapool across to the Summer Isles and north over the Coigach to the distinctive peaks of the Assynt, as well as more distant views to Skye and the Outer Hebrides, conditions permitting.

A more direct but at times steeper route rises east from Culnacraig in just two kilometres to the ridge's southwestern peak of Speicein nan Garbh Choireachan (738 metres).

Some walkers may be tempted to use one of the above-mentioned starting points, then descend via the other before completing the loop via part of the "Postman's Path", which follows the coast from Culnacraig to Strathcanaird.

Burn crossings may be difficult or even impossible in spate, in high summer vegetation may obscure the path and at the Strathcanaird end, bogs add to the difficulties.
