Ben Donich or Beinn Dòmhnaich is a mountain located in the Arrochar Alps, near Loch Goil in Argyll and Bute.

[1][2] At 847 metres Ben Donich, is the highest mountain on the Ardgoil peninsula.

It is a fairly extensive mountain, essentially a square pyramid with its summit at the centre of four ridges.

To the north-west a ridge runs down to Gleann Mòr, whilst a further ridge kicks off to the south of the summit, dropping down into the wooded glen containing the Donich Water river.

The summit (847 metres) of Ben Donich, at grid reference NN218043, also boasts an Ordnance Survey trig point.
