Yucamane, Yucamani^[2] or Yucumane^[3] is an andesitic stratovolcano in the Tacna Region of southern Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of the three volcanic belts of the Andes generated by the subduction of the Nazca plate beneath the South America plate. Peru's active volcanoes Ubinas, Sabancaya and El Misti are also part of the Central Volcanic Zone.

Yucamane, together with the volcanoes Yucamane Chico and Calientes farther north, forms a Pleistocene volcanic group. Yucamane is constructed mainly by lava flows with subordinate pyroclastic deposits, and it has a well preserved summit crater with fumarolic activity.

The volcanic group was active in the Pleistocene epoch, with the Holocene featuring several explosive eruptions occurring at Yucamane proper and effusive eruptions at Calientes. The last dated eruption of Yucamane occurred 1,320 BCE; whether there were historical eruptions is unclear as some eruptions attributed to Yucamane probably took place at Tutupaca.
