Hyogong of Silla (885–912) (r. 897–912) was the 52nd ruler of the Korean kingdom of Silla. He was the illegitimate son of King Heongang by Lady Uimyeong. He married the daughter of Ichan Ugyeom. His reign saw the collapse of Silla's authority across its northern and western provinces, as rebel warlords such as Gung Ye and Gyeong Hwon rose to power. This period, known as the Later Three Kingdoms saw the breakup of Silla, as the previously defeated Goguryeo and Baekje were revived as Taebong and Hubaekje across what had once been the western and northern provinces of Unified Silla.^[1][2]

In 905, Silla lost its holdings to the northeast of Jungnyeong pass. In 907, Gyeon Hwon's Hubaekje forces seized ten castles to the south of Ilseon. Faced with these defeats, the king turned to drink and neglected state affairs. Upon his death in 912, he was buried to the north of Sajasa temple.
