Selkirkshire is a county of Scotland in the southern uplands, bounded on the west and north by Peeblesshire, on the north by Midlothian, east and southeast by Roxburghshire, and southwest by Dumfriesshire. The area is 267 square miles.
It is principally a pastoral region, with great rounded hills, the highest points lying along the western and southwestern borders. The region is drained by the Tweed and its tributaries, chief of which are the Ettrick and the Yarrow. St Mary's Loch is chief among a number of lakes.
The only burghs are Selkirk, the capital, and Galashiels, on the Tweed.
