Princess Caoguo (or Princess of the Cao State; 1317–1350), personal name Zhu Fonü, was the second elder sister of Zhu Yuanzhang, the founding emperor of the Ming dynasty. She was the mother of Li Wenzhong, Prince of Qiyang, one of the most renowned founding generals of the dynasty.

Although Zhu Fonü did not achieve great deeds or drive historical events, she was honored for her close association with historical figures Zhu Yuanzhang and Li Wenzhong. After her death, Zhu Yuanzhang enfeoffed her as Princess Xiaoqin, emphasizing her filial piety.
