Loch Bràigh Horrisdale is a small, irregular shaped, freshwater loch in Wester Ross, in the north west of Scotland. The loch lies approximately 2 mi (3.2 km) south southeast of the village of Badachro and is close to the Fairy Lochs.

An in-river hydro-electric scheme down-stream of the loch has been proposed. As a result of this, an environmental assessment of the fish and fish habitat of the loch and its outflow was commissioned. The assessment was reported in 2014. A full EIA planning application for the 2MW scheme was lodged with Highland Council by Three Lochs Hydro Ltd on 28 July 2016.

The loch was surveyed on 6 August 1902 by T.N. Johnston and John Hewitt and later charted as part of the Sir John Murray's Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897-1909.
