Xiong Xun (Chinese: 熊徇, died 800 BC) was from 821 to 800 BC the monarch of the state of Chu during the Western Zhou dynasty of ancient China.
Like other early Chu rulers, he held the hereditary noble rank of zi (子) first granted to his ancestor Xiong Yi by King Cheng of Zhou.
However, when Xiong Shuang died in 822 BCE, the remaining three brothers fought one another for the throne.
Xiong Xun was ultimately victorious and ascended the throne, while Xiong Xue was killed and Xiong Kan escaped to Pu (濮).
