Zhang Bin (Chinese: 張賓; died 323), courtesy name Mengsun (孟孫), formally Marquess Jing of Puyang (濮陽景侯), was a key strategist for Shi Le (Emperor Ming), the founder of China's Later Zhao dynasty.
In 311, when Shi, who was then a Han-Zhao general who was winning many battles but failing to hold territory, considered capturing the region between the Yangtze River and the Han River, it was Zhang who advised him against the plan, apparently reasoning that Shi's army was suitable for mobility on the plains, not the river- and lake-filled region near the Yangtze.
In summer 312, it was at Zhang's suggestion that Shi finally occupied Xiangguo (襄國, in modern Xingtai, Hebei) and held it permanently as his headquarters.
For the next few years, while he was ostensibly a Han-Zhao general, with Zhang's assistance he expanded the territory he held to most of the area north of the Yellow River.
In 319, after Shi declared independence from Han-Zhao and its new emperor Liu Yao, thus creating Later Zhao, Zhang served as the prime minister.
