Southwestern Mandarin, excluding New Xiang

Southwestern Mandarin (simplified Chinese: 西南官话; traditional Chinese: 西南官話; pinyin: Xīnán Guānhuà), also known as Upper Yangtze Mandarin (simplified Chinese: 上江官话; traditional Chinese: 上江官話; pinyin: Shàngjiāng Guānhuà), is a primary branch of Mandarin Chinese spoken in much of central and southwestern China, including in Sichuan, Yunnan, Chongqing, Guizhou, most parts of Hubei, the northwestern part of Hunan, the northern part of Guangxi, and some southern parts of Shaanxi and Gansu. Some forms of Southwest Mandarin are not entirely mutually intelligible with Standard Mandarin Chinese or other forms of Mandarin.

Varieties of Southwestern Mandarin are spoken by roughly 200 million people. If removed from the larger "Mandarin Chinese group", it would have the 8th-most native speakers in the world, behind Mandarin itself, Spanish, English, Hindi, Portuguese, Arabic and Bengali.
