The Tu (土) people are an ethnic group. They form one of the 56 ethnic groups officially recognized by the People's Republic of China. Most of them live in Qinghai province, some of them in Gansu province.

They call themselves "Tsagaan mongghol" , which literally means White Mongols, and are closely related to the Mongols. However, they are classified as a separate minority in the Peoples' Republic of China, partly due to the fact that they have intermingled with the Tibetan and Turkic people. They don't have a script until recently.
