Mount Liupan (Chinese: 六盘山; pinyin: Lìupán Shān) is a mountain range in northwestern China, located mostly in southern Ningxia Hui Autonomous Region. It marks the southwestern boundary of the Ordos Basin.
Its southern section is known as Mount Long (Chinese: 陇山; pinyin: Lǒng Shān), which strides southeast through eastern Gansu and western Shaanxi province before joining into the Qinling Mountains, giving rise to regional names like "Longxi" (陇西, lit. "west of Mount Long"), "Longdong" (陇东, "east of Mount Long", referring to the Jing River valley basin region around eastern Pingliang, southern Qingyang and northern Xianyang) and "Longnan" (陇南, "south of Mount Long"). It is the western boundary of the Guanzhong Plain, and is also the source of the Qian River (千河), a left tributary of the Wei River that flows through the prefectural city of Baoji.
