Abriachan (/əˈbriːəxən/; Gaelic: Obar Itheachan), is a village in the Highland council area of Scotland.

It is situated high above the western shore of Loch Ness, 15 km to the south-west of the city of Inverness.

There are no schools in Abriachan, so children travel by bus into Inverness or to Dochgarroch or Tomnacross for their education.

At the bottom of the Abriachan hill, where the Kilianan stream meets Loch Ness, is Abriachan Garden Nursery, with a woodland walk and plant selling area.

Abriachan post office opened on 25 July 1882,[1] and for many years from the early 1960s was run by Katharine Stewart and her family.
