Kou Zhun (c. 961 – 24 October 1023), courtesy name Pingzhong, was a much-praised official of China's Northern Song dynasty.

Once, Emperor Taizong got offended and decided to leave, but Kou Zhun grabbed his robe and forced him to sit down and finish listening.

In 1004, during Emperor Zhenzong's reign, the Liao forces from the North initiated a major invasion and came surprisingly close to the Song capital.

When other officials such as Wang Qinruo suggested that the emperor desert the city and find a new capital in Southern China, Kou Zhun suggested the emperor come to the front line to boost the Song army's morale.

Emperor Zhenzong listened to Kou Zhun's suggestion, and the Song forces successfully resisted the Liao invasion, ending in the Chanyuan Treaty.
