Loch Torridon (Scottish Gaelic: Loch Thoirbheartan) is a sea loch on the west coast of Scotland in the Northwest Highlands. The loch was created by glacial processes and is in total around 15 miles (25 km) long. It has two sections: Upper Loch Torridon to landward, east of Rubha na h-Airde Ghlaise, at which point it joins Loch Sheildaig; and the main western section of Loch Torridon proper. Loch a' Chracaich and Loch Beag are small inlets on the southern shores of the outer Loch, which joins the Inner Sound between the headlands of Rubha na Fearna to the south and Red Point to the north.
The name Thoirbhearta has a similar root to Tarbert and indicates a place where boats were dragged overland.
