Emperor Huizong of Song (7 June 1082 – 4 June 1135), personal name Zhao Ji, was the eighth emperor of the Song dynasty of China and the penultimate emperor of the Northern Song dynasty. He was also a very well-known painter, poet and calligrapher. Born as the 11th son of Emperor Shenzong, he ascended the throne in 1100 upon the death of his elder brother and predecessor, Emperor Zhezong, because Emperor Zhezong's only son died prematurely. He lived in luxury, sophistication and art in the first half of his life. In 1126, when the Jurchen-led Jin dynasty invaded the Song dynasty during the Jin–Song Wars, Emperor Huizong abdicated and passed on his throne to his eldest son, Zhao Huan while Huizong assumed the honorary title of Taishang Huang (or "Retired Emperor"). The following year, the Song capital, Bianjing, was conquered by Jin forces in an event historically known as the Jingkang Incident. Emperor Huizong and Emperor Qinzong and the rest of their family were taken captive by the Jurchens and brought back to the Jin capital, Huining Prefecture in 1128. The Emperor Taizong of Jin, gave the former Emperor Huizong a title, Duke Hunde (literally "Besotted Duke"), to humiliate him. After Zhao Gou, the only surviving son of Huizong to avoid capture by the Jin, declared himself as the dynasty's tenth emperor as Emperor Gaozong, the Jurchens used Huizong, Qinzong, and other imperial family members to put pressure on Gaozong and his court to surrender. Emperor Huizong died in Wuguocheng after spending about nine years in captivity. He, along with his successors, were blamed for the Song dynasty's decline.

Although he wasn't a competent administrator, Emperor Huizong was known for his promotion of Taoism and talents in poetry, painting, calligraphy and music. He sponsored numerous artists at his imperial court, and the catalogue of his collection listed over 6,000 known paintings.
