Zhao Dezhao (趙德昭) (951 – 26 August 979) was an imperial prince of the Chinese Song dynasty.

However, he did not succeed the throne after his father, as his uncle Emperor Taizong assumed power.

The guards told him that blades were not allowed in the palace, so Zhao Dezhao fetched a knife for cutting fruits, went to his room and then proceeded to slice his throat killing him.

[1][2] Upon hearing about the suicide, Emperor Taizong was very saddened and hugged the corpse crying while saying "Silly boy, how did you come to this depravity?

"[2] However, as official history may not be trusted in events like this, some historians suspect that Zhao Dezhao was either murdered or forced to commit suicide by his uncle, who possibly was also involved in the deaths of Zhao Dezhao's father and younger brother.
