Aird and Loch Ness is one of the 21 wards used to elect members of the Highland Council. It includes Loch Ness, the town of Beauly, and the village of Fort Augustus. It elects four Councillors.
A by-election was originally scheduled to take place on 5 November 2020 to elect one councillor after the death of George Cruickshank. However, it was postponed to 11 March 2021.
A by-election was triggered by the resignation of Drew Hendry in July 2015, following his election as an MP.
