Ip Chun (simplified Chinese: 叶准; traditional Chinese: 葉準; pinyin: Yè Zhǔn; born July 1924), also spelled as Yip Chun or Yip Jun, is a Chinese Wing Chun martial artist. He is the oldest son of Yip Man (Ip Man).

Ip began studying Wing Chun with his father when he was seven years old. In 1949, after the Communists established the People's Republic of China on the mainland, Ip's father left for Hong Kong and Ip, then 24, remained in Foshan to continue his studies in university. Ip studied Chinese history, philosophy, poetry, traditional music, and Buddhism.

By 1950, Ip had completed his studies and he chose teaching as a profession. In addition to teaching Chinese history, music and science, Ip also helped the Chinese Foshan Entertainment Department organize opera plays. During that time, he was awarded "The Person with the Most Potential in Chinese Art" award for his research in music. However in 1962, due to the Cultural Revolution, Ip and his younger brother, Ip Ching, were forced to leave Fo Shan and move to Hong Kong to join their father.
