Ograzhden (Огражден, pronounced [oˈɡraʒdɛn] in Bulgarian and [ˈɔɡraʒdɛn] ⓘ in Macedonian) is a mountain range shared by southwestern Bulgaria and southeastern North Macedonia.

To the west the valley of the river Turia (left tributary of Strumeshnitsa) separates it from Dragolevska Mountain.

The highest summit of the mountain is Ograzhdenets at 1744 m, located in North Macedonia, about 3 km west of the border.

In the Bulgarian part the highest peak is Bilska Chuka 1644 m, about 2 km north of the village of Baskaltsi.

Ograzhden is formed by broken metamorphic rocks[1] — gneiss and various types of schists, which are easily susceptible to weathering and erosion.
