Great Shu (Chinese: 大蜀; pinyin: Dàshǔ), known in historiography as the Former Shu (Chinese: 前蜀; pinyin: Qiánshǔ) or occasionally Wang Shu (王蜀), was a dynastic state of China and one of the Ten Kingdoms during the Five Dynasties and Ten Kingdoms period.

It existed from 907 to 925 CE.

The country's name changed from "Shu" to "Han" (Chinese: 漢; pinyin: Hàn) in 917–918, which is not to be confused with another contemporaneous kingdom during the same Five Dynasties and Ten Kingdoms period, the Southern Han (traditional Chinese: 南漢; simplified Chinese: 南汉; pinyin: Nán Hàn), 917–971 CE.
