Ouyang Gao 歐陽高, courtesy name Ziyang 子陽, was a Confucian scholar of the Former Han period 前漢 (206 BCE-8 CE).
He hailed from Qiancheng 千乘 (modern Gaoqing 高青, Shandong) and was a great-grandson of Ouyang Sheng 歐陽生 (courtesy name Ouyang Hebo 歐陽和伯), a disciple of Fu Sheng 伏勝, an expert of the Confucian Classic Shangshu 尚書 "Book of Documents". Ouyang Gao was an erudite (boshi 博士) at the National University (taixue 太學) and a teacher of Xiahou Sheng 夏侯勝.
The interpretation of the Shangshu by Ouyang Gao opened an own tradition, the School of Ouyang. His disciples Lin Zun 林尊 and Ping Dang 平當 created their own sidelines of the Ouyang School.
