Puno is a region in southeastern Peru. It is bordered by Bolivia on the east, the Madre de Dios Region on the north, the Cusco and Arequipa regions on the west, the Moquegua Region on the southwest, and the Tacna Region on the south. Its capital is the city of Puno, which is located on Lake Titicaca in the geographical region known as the Altiplano or high sierra.

The Puno region is located in the Collao Plateau. The western part of Lake Titicaca, which is the world's highest navigable lake, is located in the region. The Andean mountains make up 70% of the region's territory, and the rest is covered by the Amazon rainforest.

The climate is cold and dry, with a four-month rain season. On the other hand, the climate of the rainforest is warm. The water resources are taken from the Lake Titicaca, 50 lagoons and more than 300 rivers. There is also an important potential in underground waters.
