Zhao Mengfu ( Wade?iles: Chao Meng-fu) was a prince and descendant of the Song Dynasty's imperial family, and a Chinese scholar, painter and calligrapher during the Yuan Dynasty.

He was married to Guan Daosheng, who was also an accomplished poet, painter and calligrapher. His rejection of the refined, gentle brushwork of his era in favour of the cruder style of the eighth century is considered to have brought about a revolution that created the modern Chinese landscape painting. He was known for his paintings of horses.
