Xu Yang (simplified: 许玚, traditional: 許玚, pinyin: Xǔ Yáng) was the cousin of Xu Jing and Xu Shao. He served as Chancellor of Chen State (陳國相). When Dong Zhuo held power, Xu Yang plotted with Kong Zhou (孔伷) to attack him; Xu Jing, fearing implication, fled to Kong Zhou. Few other details are recorded in the sources.
