Emperor Duānzōng (Chinese: 端宗) (1268 – 8 May 1278) was the eighth and penultimate emperor of the Southern Song Dynasty of China who reigned from 1276 to 1278 and died at the age of ten. He was also known as the "Nation Establishing Duke " (建國公).
Born Zhào Xià (趙昰,"昰" same as "夏", means "大"(great)，not "summer"), his father was sixth Southern Song Emperor Duzong. He became Prince Ji (吉王) in 1274 and Prince Yi (益王) in 1276. Enthroned as emperor at Fuzhou on 14 June 1276, his only era took the name of Jǐngyán (景炎 literally: bright flame). Duanzong's temple name means "Final Ancestor".
Duanzong's younger brother Emperor Gong of Song had been captured after the Mongol invasion of Lin'an (present day Hangzhou) in 1276. Duanzong, along with one of his younger brothers Zhào Bǐng (赵昺/趙昺), escaped to Fujian and established the seat of the government in Fuzhou. In 1278, the Mongol forces were about to break through Song's last line of defense, forcing Duanzong to flee. Accompanied by ministers such as Lu Xiufu, Duanzong boarded a ship and fled to the province of Guangdong. Thereafter he stayed temporarily in Hong Kong where the Sung Wong Toi (literally: Terrace of the Sung kings) in Kowloon City commemorates this event.
In March 1278, whilst fleeing from the Mongols, Duanzong fell from a boat and almost drowned. After his rescue, he became ill and died a few months later in Gangzhou (碙州) (modern-day Lantau Island, Hong Kong).
He was succeeded by his younger brother, Emperor Huaizong of Song.
