Ding Yuan (died 189) was a regional governor and minor warlord during the late Han Dynasty period of Chinese history. In 189, both he and Dong Zhuo were summoned into the capital Luoyang with their individual troops to assist in the struggle against the powerful eunuch faction. Ding Yuan, however, was eventually killed by his trusted aide Lü Bu, who had been bought over by Dong Zhuo.
