Blackhope Scar is a Graham of 651.8 m in Midlothian, Scottish Borders. It is also on the county tops list, as the highest point of its historic county.
It counts towards four lists: Grahams, Donalds, Marilyns and county tops. All four of its nearest neighbours are higher, up to Broad Law at 840.1 m. It is one of only two register hills in the Firth of Forth to the River Tweed region, with Windlestraw Law. All four of its nearest neighbours lie to the south, so it stands at the northern edge of its group. The summit is marked by a trig point.
