Black Meldon is a prehistoric site, a hillfort near the village of Lyne and about 4 miles (6 km) west of Peebles, in the Scottish Borders, Scotland.

[1] The hillfort on the neighbouring hill White Meldon is about 1 mile (1.6 km) to the east, on the other side of Meldon Burn.

The roughly oval fort on the summit is 73 metres (240 ft) north–south and 40 metres (130 ft) west–east, defined by a boundary wall, which is now a band of debris about 3 metres (10 ft) wide.

On the north, west and south sides there is the debris of an outer wall.

[3] Within the fort, at least seven ring-groove houses exist, five lying in a straight line along the north-south axis, ranging from 7m to 10m in diameter.
