Fan Ye (398–445 or 446[note 1]), courtesy name Weizong (蔚宗), was a Chinese historian and politician of the Liu Song dynasty during the Southern and Northern dynasties period. He was the compiler of the historical text Book of the Later Han. The son of Fan Tai (范泰), Fan Ye was born in present-day Shaoxing, Zhejiang, but his ancestral home was in Nanyang, Henan.
He was a noted atheist who heavily criticised Buddhism, Yin and Yang, and the concept of the Mandate of Heaven. To this end he cited Zhang Heng's scientific studies as evidence.
Fan has a biography in the Book of Song.
