Zhao Tong (206-239) was a military general of Shu Han during the Three Kingdoms period of Chinese history. Zhao Tong was the eldest son of Zhao Yun. He and his brother Zhao Guang informed Jiang Wei and the Shu ruler Liu Shan of their father's death and together guarded their father's tomb (which was located at Mount Jinping). In Luo Guanzhong's historical novel Romance of the Three Kingdoms, he became a general after his father died.
