Marquess Kang of Han (韩康子 / 韩国宣子, Hán Khang tử; personal name Han Hu 韩虎; d. 424 BC), was the penultimate hereditary patriarch of the Han clan in the State of Jin before the formal Tripartite Partition of Jin.
In 453 BC, facing extinction under the tyrannical Jin hegemon Zhi Bo (智伯), Marquess Kang secretly allied with Wei Huanzi and Zhao Xiangzi (Zhao Xiangzi) at the epic Battle of Jinyang. In a midnight masterstroke, Han and Wei turned the channeled river waters back upon Zhi Bo’s camp, annihilating the Zhi clan, partitioning Jin, and laying the foundation for the independent State of Han.
