Scottish Marches was the term used for the Anglo-Scottish border during the late medieval and early modern eras, characterised by violence and cross-border raids. The Scottish Marches era came to an end during the first decade of the 17th century following the union of the crowns of England and Scotland.

The Anglo-Scottish border or English-Scottish border (known locally as simply The Border) is the official border and mark of entry between England and Scotland. It runs for 96 miles (154 km) between Marshall Meadows Bay on the east coast and the Solway Firth in the west. It is Scotland's only land border. England shares a longer border with Wales.
