The Later Zhou (; simplified Chinese: ; traditional Chinese: ; pinyin: Hu Zhu) was the last in a succession of five dynasties that controlled most of northern China during the Five Dynasties and Ten Kingdoms period, which lasted from 907 to 960 and bridged the gap between the Tang Dynasty and the Song Dynasty.

Guo Wei (Chinese: 郭威) (10 September 904 – 22 February 954), also known by his temple name Taizu (太祖), was the founding emperor of imperial China's short-lived Later Zhou during the Five Dynasties and Ten Kingdoms period, reigning from 951 until his death.

Nicknamed "Sparrow Guo" (郭雀兒) after a sparrow-shaped tattoo on his neck, he rose to a high position in the Later Han as an assistant military commissioner. He founded the Later Zhou in 951.
