The Ziama Massif is a forested mountain range and nature reserve in the Nzérékoré Region of south-eastern Guinea.

The Ziama Massif extends from north-east to south-west, continuing southwards into Liberia as the Kpo Range.

The forested landscape includes valleys, plateaus, rounded ridges, rocky peaks, sheer cliffs and granite outcrops.

[2] The Ziama Massif is part of the Guinean montane forests ecoregion, and harbours a flora and fauna distinct from the surrounding lowlands.

It is considered a relict of the diminishing Upper Guinean forest formation.
