Zhou Zong (周宗), courtesy name Juntai (君太), was an official of the Chinese Five Dynasties and Ten Kingdoms period state Southern Tang. Zhou was a close associate of its founding emperor Emperor Liezu and thus was honored by Emperor Liezu (Xu Zhigao/Li Bian) and his son and successor Emperor Yuanzong (Xu Jingtong/Li Jing). His two daughters became successive empresses (known as Empress Zhou the Elder and Empress Zhou the Younger) for Emperor Yuanzong's son and successor, Southern Tang's final emperor Li Yu (often known as Li Houzhu).
