Marquess Lie of Zhao (died 400 BCE), personal name Zhao Ji, was the founding marquess of the Zhao state during the Warring States period of China.
During his reign, Marquess Lie employed righteous government officials, including Gong Zhonglian (公仲連), Niu Xu (牛畜), Xun Xin (荀欣) and Xu Yue (徐越), whilst he followed the virtuous "Way of the King" (王道).
When cavalry from the Zhongshan state attacked Zhao, Marquess Lie allied himself with Marquess Wen of Wei to counterattack Zhongshan.
In the sixth year of Marquess Lie's reign (403 BCE), Zhao, along with Wei and Han, became fiefs of the Eastern Zhou dynasty as a result of the Partition of Jin.
Since his son Zhao Zhang was underaged at the time, Marquess Lie's younger brother, Duke Wu of Zhao (趙武公), succeeded him as ruler.
