Duke Ling of Qin (Chinese: 秦靈公; pinyin: Qín Líng Gōng; died 415 BC), personal name unknown, was from 424 to 415 BC the monarch of the Qin state.
In 425 BC Qin general Chao (鼌) and other ministers attacked and besieged Duke Huai, and Duke Huai committed suicide.
As Duke Huai's son Crown Prince Zhaozi (昭子) died early, the ministers installed Duke Ling, Zhaozi's son, on the throne.
[1][2] In 419 BC, the sixth year of Duke Ling's reign, Qin attacked the Wei state at the city of Shaoliang (少梁, in present-day Hancheng, Shaanxi).
[1][2] Duke Ling reigned for 10 years and died in 415 BC.
