Mu Guiying (穆桂英) is a legendary heroine from ancient China's Northern Song dynasty and a prominent figure in the Generals of the Yang Family legends.

Brave, resolute and loyal, Mu is the cultural symbol of a steadfast woman.

Mu played a huge part in the following battle against the Khitan forces, especially in breaking their previously unstoppable Heavenly Gate Formation (天門陣).

Mu Guiying is sometimes venerated as a door goddess, usually in partnership with Qin Liangyu.
