The Yi or Lolo people are an ethnic group found mainly in Yunnan; southwest China. Numbering 8 million; they are the seventh largest of the 55 ethnic minority groups officially recognized by the People's Republic of China. They live primarily in rural areas of Sichuan; Yunnan; Guizhou; and Guangxi; usually in mountainous regions.

The Yi speak Yi; a language closely related to Burmese.

The Yi are more rural than their urbanised Naxi neighbours. Like the Naxi; they are a Tibeto-Burman people who may have originally migrated from the northwest.

Yi women generally wear a colourful long-sleeved blouse and vest over long skirts; pleated from the knees. Headgear varies according to marital status; with unmarried girls favouring an elaborately multi-coloured head-dress decorated with cowries or glass beads; while older married women wear a more sombre black hat.
