Duan Ye (simplified Chinese: 段业; traditional Chinese: 段業; pinyin: Duàn Yè; died 401) was the founding prince of China's Northern Liang dynasty. He was of Han ethnicity. After establishing the Northern Liang in 397, he was overthrown by Juqu Mengxun in 401.

Originally a commandery governor of the Later Liang dynasty, Duan Ye was persuaded by Juqu Nancheng (沮渠男成) to accept the leadership role of the Lushuihu generals who had rebelled against the Later Liang. During his reign, the Juqus were powerful, and in 401, Duan Ye was tricked by Juqu Mengxun into executing Juqu Nancheng. Juqu Mengxun then used this as the excuse to start a coup against Duan Ye, killing him and replacing him as king. Duan Ye was described as a kind but weak ruler who was unable to keep his subjects in check, and who overly trusted witchcraft and magic.
