The Uluguru mountains are a mountain range in eastern Tanzania, named after the Luguru tribe. The main portion of the Uluguru mountains is a ridge running roughly north-south and rising to 2,630 metres (8,600 ft) altitude at its highest point. On the main Uluguru range, 50 villages touch the forest boundary and over 151,000 people are found within the mountain area, often at increasing densities at higher altitudes up to the forest boundary.

The Ulugurus lie 200 km inland from the Indian Ocean. They are part of a chain of mountains in eastern Africa collectively called the Eastern Arc Mountains, which include the Taita Hills, Pare Mountains, Usambara Mountains, Nguru Mountains, Rubeho, Ukaguru, Udzungwa Mountains and Mahenge Mountains. The forests of the mountains provide the water catchment areas for the streams and rivers. This water flows mainly from the forest-capped peaks of the Ulugurus into streams joining to form the Ruvu River.
