Cintia knizei is a small alpine cactus native to the high Andes of Bolivia. The plant was discovered by Karel Kníže in 1969 at an elevation of 4,000 m (13,000 ft) near Otavi, in Potosí Department, Bolivia. However, it was not formally described until 1996 by Jan Říha. The genus is named after the town of Cinti in Chuquisaca Department.
