Zhongjunjiang (Chinese: 中軍將) or Jiangzhongjun was the military leader and the prime minister of the ancient Chinese state of Jin. Literally, the word Zhongjunjiang means "General of central army". The post originally was named "Situ" (司徒). Zhongjunjiang was also known as "Jiangjun" (將軍), "Dazheng" (大政, 太政, 大正) and "Yuanshuai" (元帥). Since Zhao Dun's term as Zhongjunjiang, the post's jurisdiction was widened and its holder automatically obtains the regency of Jin. Historical evidence also indicate that Zhongjunjiang had the legislative power.
