Chachakumani, Mountain summit in La Paz Department, Bolivia.

Chachakumani is a summit in the Andean range located at 6,074 meters above sea level, featuring steep terrain and exposed rock throughout its ascent. The peak sits on the Cordillera Real massif with angular ridges and narrow sections that characterize its upper slopes.

Chachacomani was first climbed on 8 January 1947 by F. Fritz, F. Buchholtz, G. Moller, D. Doore, I. Paz and G. Sanjinez, a German-Bolivian team. On 14 July 2012 the Catalan Xavier Santos Rillo and the Bolivian Aldo Riveros made the first Catalan and Spanish ascent, following the southwest glacier route. The mountain lies in Larecaja Province, La Paz Department, southeast of Chearoco.

The name may derive from Quechua chachakuma, a medicinal plant, though the peak is also called Nevado Chachacomani. Its sheltered valleys create microclimates with lakes that support many bird species. The mountain is among the least climbed in the Cordillera Real, and its height has never been measured precisely, possibly varying by 20 metres.

Chachacomani is reached from Guanay Municipality in Larecaja Province, and the peak is hidden among surrounding mountains, so approach routes need careful planning. The official height of 6,074 m is uncertain by up to 20 m, and digital elevation models give 6,038 to 6,084 m. The first ascent, on 8 January 1947, went by a route that later climbers can research before setting out.

Chachacomani is said to be one of the least climbed peaks in the Cordillera Real, and its height has never been measured precisely: digital elevation models give 6,038 m (SRTM), 6,043 m (ASTER) and 6,084 m (TanDEM-X) against the official 6,074 m. Its first ascent was made on 8 January 1947 by F. Fritz, F. Buchholtz, G. Moller, D. Doore, I. Paz and G. Sanjinez.
