Zhou Ehuang (周娥皇) (c. 936 – 8 December 964), posthumously named Queen Zhaohui (昭惠國后), was a queen consort of imperial China's short-lived Southern Tang state during the Five Dynasties and Ten Kingdoms period. Her husband was Li Yu, Southern Tang's third and last ruler. She is best known as Queen Zhou the Elder (大周后) to distinguish from her younger sister Queen Zhou the Younger whom Li Yu married after her death. A musical genius and pipa virtuoso, she is suspected to be the subject of many of Li Yu's enduring love poems.
