Megget is a former chapelry or parish containing the valley of Megget Water, now forming the westernmost part of the parish of Yarrow, Selkirkshire in the Scottish Borders area of Scotland. The centre of the valley is 19 miles west of Selkirk.
The district is bordered on the west by the parish of Tweedsmuir, on the north-west by Drumelzier and on the north by Manor (all in Peeblesshire). On the east side it is joined to the rest of the present parish of Yarrow, but formerly the parish boundary with Yarrow ran southwards from Black Law to Deer Law to Cappercleuch burn thence to St. Mary's Loch and continued down the west shore of the loch for almost a mile to Mare Cleuch by the Rodono Hotel. It is bounded on the south by Ettrick in Selkirkshire and on the south-west by Moffat in Dumfriesshire. Megget Stone lies on the western parish boundary, with Tweedsmuir.
It is about 7 miles long north to south and about 6 miles wide with an area of 14,500 acres.
The population of Megget in 1861 was 53 and in 1901 was 73. At the latest census (in 2011) the population of Megget was around 50.
The parish of Megget derived its name from the river Megget, which took its name from the whey colour of its waters (Gaelic or old Welsh). Until 1891 it was part of Peeblesshire and thus part of Tweeddale, however “the water of Meggit is the only water in Tweeddale, that pays no tribute to Tweed; but runs from the south-east, some five miles, and ends its course in the bosom of St Mary Loch, and from thence, with Yarrow, watereth the wοόdy banks of the Forrest” (namely Ettrick Forest – the county of Selkirkshire).
