Sajama National Park is a national park located in the Oruro Department, Bolivia. It borders Lauca National Park in Chile.

The park lies within the Central Andean dry puna ecoregion. It features a spectacular Andean landscape, with elevations ranging from 4,200 to 6,542 metres (13,800 to 21,463 ft). It contains the snowy cone of Nevado Sajama, the highest mountain in Bolivia. The park also includes the Nevados de Payachata. On July 1, 2003, it was added to the UNESCO World Heritage Tentative List due to its universal cultural and natural significance.

The reserve is jointly administered by park service officials and the indigenous people, the Aymara. It has proved an example of sustainable resource use and healthy tourism. As all protected areas in Bolivia are inhabited, nature conservation is not possible against the will of the local people. It is necessary to take their traditional rights, existing value systems and social organisation into account. Joint administration
