Duke Ai of Qin (Chinese: 秦哀公; pinyin: Qín Āi Gōng, died 501 BC), personal name unknown, was from 536 to 501 BC the duke of the Qin state.
[1][2] In 523 BC, Duke Ai betrothed his daughter Bo Ying to Crown Prince Jian of the State of Chu, Qin's ally.
However, Fei Wuji saw that the princess was beautiful and persuaded King Ping to take her as his own wife.
It is said that Duke Ai originally rejected the request, but finally agreed to help after Shen Baoxu wailed for seven days outside the Qin palace without eating.
[1][2] Duke Ai sent generals Zipu (子蒲) and Zihu (子虎) with 500 chariots to Chu.
