Qian Yongchang (Chinese: 钱永昌; 1936 – 1995) was a Chinese serial killer who killed 15 people from 1959 to 1995 across three provinces, out of a self-professed contempt for how society had treated him. At the time of his arrest, Qian's advanced age led to him being labeled the country's oldest active serial killer, as well as one of the longest active, with his killing spree lasting more than three decades and a half. For his last crimes, he was convicted, sentenced to death and summarily executed.
