Greenlaw is a town and civil parish situated in the foothills of the Lammermuir Hills on Blackadder Water at the junction of the A697 and the A6105 in the Scottish Borders area of Scotland. At the 2001 census, the parish had a population of 661. It was first made the county town of Berwickshire in 1596, and was the first town to take on this role since the English took Berwick in 1482. At that time, Greenlaw was situated about a mile south of the present village, atop a hill - the 'Green Law'. This area is now known as Old Greenlaw.
