The Ch'iyar Juqhu River (Aymara Ch'iyar Juqhu Jawira, ch'iyara black, juqhu muddy place, jawira river, "black muddy river", Hispanicized spellings Chiar Jokho, Chiar Joko) is a Bolivian river east of Lake Titicaca in the La Paz Department. It originates in the Cordillera Real near the peaks of the 6,127 m high Ch'iyar Juqhu which is probably named after the river or the region around it and the 5,871 m high Qalsata and flows down towards the Altiplano.
