Xiong Ai (Chinese: 熊艾, reigned c. 977 BCE) was the second ruler of the state of Chu during the early Western Zhou dynasty of ancient China. He succeeded his father Xiong Yi, who was enfeoffed by King Cheng of Zhou and granted the hereditary noble rank of zi (子).^[1]

Ancient Chinese texts recorded that King Zhao of Zhou, the grandson of King Cheng of Zhou, led an expedition against Chu, but Zhou was defeated and King Zhao himself drowned in the Han River in 977 BCE. It is generally believed that Xiong Ai was the monarch of Chu at the time.^[2]

Xiong Ai was succeeded by his son, Xiong Dan.^[1]
