Dugu Xin (Chinese: 獨孤信; 503 – 24 April 557),[2][3] Xianbei name Qimitou (期彌頭), known as Dugu Ruyuan (獨孤如願) before 540,[2] was a general and official during the chaotic Northern and Southern dynasties period of imperial China.

Despite an early debacle (after which he fled to and stayed for three years in the southern Liang dynasty before returning to the northwest), he captured the former Northern Wei capital Luoyang from Eastern Wei in 537.

When the Northern Zhou dynasty replaced Western Wei, Dugu Xin was created Duke of Wei (衛國公), but was soon forced to commit suicide by the powerful regent Yuwen Hu.

In fact, every Chinese emperor for 3 centuries (from 604 to 907, with the exception of Wu Zetian and self-proclaimed rebels) was descended from him.

In 583, the Empress built a temple dedicated to his memory in the capital Daxing, the remains of which were discovered in 1997 on the campus of Xi'an Jiaotong University.
