Ouyang Xiu (Chinese:欧阳修;  1007 – 1072 CE), courtesy name Yongshu, also known by his art names Zuiweng (醉翁) and Liu Yi Jushi (六一居士), was a Chinese historian, calligrapher, epigrapher, essayist, poet, and politician of the Song dynasty. He was a renowned writer among his contemporaries and is considered the central figure of the Eight Masters of the Tang and Song.

His poems are generally relaxed, humorous and often self-deprecatory; he gave himself the title The Old Drunkard. He wrote both shi and cí.

Ouyang's poetry, especially the mature works of the 1050s, dealt with new themes that previous poets had avoided. These include interactions with friends, family life, food and beverages, antiques, and political themes.
