Chen Lan (died 209) was a military general serving under the warlord Yuan Shu during the late Han Dynasty period of Chinese history. Chen was the deputy commander in the attack on Xu Province. After Yuan groundlessly declared himself emperor after obtaining the Imperial Seal from Sun Ce, Chen abandoned his lord with Lei Bo. Lei and Chen then became brigands. Following the defeat of Yuan Shu, Chen and Lei both came back to pillage the remains of Yuan Shu's valuables.
