Anfeng County (安豐縣) was a county of Lujiang Commandery on the lower Yangtze and Huai–Yangtze corridor. The precise site is debated, but later local tradition places it near modern Liji Town in the Huoqiu–Gushi region on the border of modern Anhui and Henan.
The county is best known from the biography of Ding Feng, who was said to be a native of ‘Anfeng County, Lujiang Commandery’. After a long career serving all four Eastern Wu emperors and winning fame at the snow battle of Dongxing, Ding Feng was enfeoffed as Marquis of Anfeng, taking his native county as the name of his fief. Beyond this connection and its place within Lujiang’s network of riverine counties, few further details are recorded about Anfeng in the surviving sources.
