Gombe Stream National Park is a National Park in north-western Tanzania.

It borders on Lake Tanganyika, and is just south of the border with Burundi. The regional capital of western Tanganyika, Kigoma, is 10 miles (20 km) south of Gombe.

Established in 1968, Gombe is the smallest national park in Tanzania, with only 20 square miles (52 km2) of forest running along the hills of the northern shore of Lake Tanganyika.

The terrain has steep valleys, and the forest vegetation ranges from grassland to alpine bamboo to tropical rainforest.

The Park can only be reached by boat.
