The Zigong dialect (simplified Chinese: 自贡话; traditional Chinese: 自貢話; pinyin: Zìgònghuà; Wade–Giles: Tzu-kung hua) is a branch of Southwestern Mandarin, spoken mainly in Zigong, Fushun, Weiyuan, east Rongxian and some parts of Yibin, Neijiang, Longchang and other neighboring areas of Sichuan.

Also, the Minjiang dialect is spoken in a few remote towns or villages bordering Luzhou, Leshan and Yibin.

The modern Zigong dialect was formed rather recently in a great wave of immigration after the Qing dynasty.

Zigong has long been known as the "Salt Capital" for its brine extraction techniques and the attendant salt-related culture.

Hence many merchants, mainly from Hubei, Henan, Jiangxi, Fujian, Shaanxi, Shanxi and Guangdong, flooded into Zigong, bringing their Chinese varieties with them.
