Hao Chujun (郝處俊) (607–681), formally Duke of Zengshan (甑山公), was an official and general of the Chinese dynasty Tang Dynasty, serving as chancellor during the reign of Emperor Gaozong. He was known for his honesty and willingness to advise Emperor Gaozong against actions he considered unwise. One advice he gave, however (against Emperor Gaozong's plan to let his powerful wife Empress Wu (later known as Wu Zetian) serving as regent due to Emperor Gaozong's illness), drew Empress Wu's resentment, and later, after she became regent over her son Emperor Ruizong after Emperor Gaozong and Hao had both died, she had Hao's clan slaughtered.
