Gyeongjong (9 November 955 – 13 August 981), personal name Wang Chu, was the fifth ruler of the Goryeo dynasty of Korea. He was the eldest son of King Gwangjong, and was confirmed as Crown Prince in the year of his birth. He was also the maternal and paternal grandson of King Taejo.
Upon rising to the throne, Gyeongjong established the Jeonsigwa (田柴科, land-allotment system) which established the economic basis for Goryeo's bureaucracy. Following his ascension, he issued pardons for those whom his predecessor had persecuted and even reinstated their titles. Later, according to the Goryeo-sa, he avoided politics and royalty, and spent his time cavorting with commoners as well as indulging in sex or playing baduk.
