Ben Mor Coigach (Scottish Gaelic: Beinn Mhòr na Còigich) is a long, table shaped mountain in the far north-west of Scotland. It dominates the Coigach peninsula, in the county of Ross and Cromarty, 10 kilometres north-west of the town of Ullapool. It reaches a height of 743 metres (2438 feet). Its coastal location, combined with its high topographic prominence to height ratio, make it a very good viewpoint.

It is a Scottish Wildlife Trust nature reserve.
