Ren Renfa (simplified Chinese: 任仁发; traditional Chinese: 任仁發; pinyin: Rèn Rénfā; Wade–Giles: Jen Jen-fa)(1254–1327), courtesy name Zi Ming (子明), pseudonym Yueshan Daoren (月山道人 - "Taoist on the Moon Mountain"), was an expert of irrigation works, artist, and a government official during the Yuan Dynasty. He was born in the Qinglong Zhen district of Songjiang (松江青龙镇 - present day Qingpu District, Shanghai).
Ren drew some outstanding paintings of horses, people, flowers and birds. Ren's style is similar to the artists of the Tang Dynasty (608–907) and Li Gongling in Song Dynasty (1127–1279). His paintings of horses are comparable to those by Zhao Mengfu.
Ren's hydrological works include dredging the area in what is now Beijing to improve the water supply and leading a team to build embankments after the Yellow River burst its banks.
