Yue Fei (Chinese: 岳飛; March 24, 1103 – January 28, 1142), courtesy name Pengju (鵬舉), was a Chinese military general who lived during the Southern Song dynasty, known for leading Southern Song forces in the wars in the 12th century between Southern Song and the Jurchen-ruled Jin dynasty in northern China.

At the age of 30, Yue supposedly wrote his most celebrated poem, "Man Jiang Hong" ("Entirely Red River"). It reflects the raw hatred he felt towards the Jurchen-ruled Jin dynasty, as well as the sorrow he felt when his efforts to recoup northern lands lost to Jin were halted by Southern Song officials of the "Peace Faction".
