Empress Xiaoquancheng, of the Manchu Bordered Yellow Banner Niohuru clan, was a posthumous name bestowed on the wife and second empress consort of Mianning, the Daoguang Emperor. She was empress consort of Qing from 1834 until her death in 1840.

The Daoguang Emperor, also known by his temple name Emperor Xuanzong of Qing, personal name Mianning, was the seventh emperor of the Qing dynasty, and the sixth Qing emperor to rule over China proper, reigning from 1820 to 1850. His reign was marked by "external disaster and internal rebellion." These included the First Opium War and the beginning of the Taiping Rebellion which nearly brought down the dynasty. The historian Jonathan Spence characterizes the Daoguang Emperor as a "well meaning but ineffective man" who promoted officials who "presented a purist view even if they had nothing to say about the domestic and foreign problems surrounding the dynasty."
