Yang Chengfu (1883–1936) was one of the best known teachers of Yang-style tai chi Chinese martial art.

His students would go on to found successful martial arts schools of their own and helped spread Yang-style tai chi around the world.

With his older brother Yang Shaohou and colleagues Wu Jianquan and Sun Lutang, he was among the first teachers to offer tai chi instruction to the general public at the Beijing Physical Culture Research Institute from 1914 until 1928.

Among Yang Chengfu's students were famous masters such as Zhao Bin (his older brothers grandson 1906-1906) Dong Yingjie, Chen Weiming, Fu Zhongwen, Li Yaxuan (李雅轩; 1894–1976) and Cheng Man-chʻing.

Cheng Man-chʻing, perhaps the most famous outside of China, significantly shortened and simplified the traditional forms Yang taught him after his teacher's passing, reportedly to make them more accessible to larger numbers of students.
