Teuchter is a Scots word used colloquially to refer to rural Scots by urban Scots. It is particularly applied to those from the North or North-east of Scotland. Like most such cultural epithets, it can be used either jokingly or offensively.

The word has an unclear origin. One possibly apocryphal explanation is that, during the First World War, many members of the Highland regiments were pipers. A book of sheet music for the pipes is called a "tutor", and when pronounced with the aspiration of their Gaelic accents, this sounds like "teuchter".

Another possibility is the Scots word teuch (tough), for a rural person, or the Gaelic equivalent, tuath, or farmer, tuathanach.

The archetypal cartoon teuchter is Angus Og (comic), by Ewan Bain .

Interestingly, the word teuchter is the origin of part of the scientific name for a species of salmon, gyrodactylus teuchis (G. Teuchis, for short).
