William Cheung or Cheung Cheuk Hing (張卓慶, pinyin: Zhāng Zhuóqìng), born October, 1940, is a Chinese Wing Chun kung fu practitioner and currently the Grandmaster of his lineage of Wing Chun, entitled Traditional Wing Chun (TWC). He also heads the sanctioning body of TWC, the World Wing Chun Kung Fu Association.
Cheung attained a Bachelor of Economics from the Australian National University, after graduating from secondary school in Hong Kong. Cheung is a certified Doctor of Chinese Medicine under the Chinese Medicine Registration Board of Victoria, and a member of the Australian Chinese Traditional Orthopaedics Association Inc. He has also been invited as a Guest Professor to Foshan Sports University (China), and as a Senior Research Professor of the Bone Research Department to Beijing Chinese Medical University (China).
In 1951, at the age of ten, Cheung started his training in Wing Chun Kung Fu under the late Yip Man. According to Cheung, it was from 1954 to 1958 that he was a live-in student of Yip Man and inherited the complete system of Traditional Wing Chun.
Duncan Leung, a Yip Man student, says it was William Cheung who first made Wing Chun famous in Australia. "In 1957 another early student of Yip Man, William Cheung, immigrated to Australia. On the way there an incident occurred when he locked himself in the sailor cabin and fought more than 10 sailors. This got into all the newspapers and so Wing Chun was even known in Australia then."
Cheung is known for using "Egg Standing" to demonstrate his skill in weight distribution and overall control of his body. 
After moving to Melbourne, Australia to teach Traditional Wing Chun professionally in 1973, Cheung began operating a Traditional Wing Chun Kung Fu school. In 1976 he was elected the President of the Australian Kung Fu Federation.

His fight with Emin Boztepe, then a student of Keith R. Kernspecht, in 1986, at a seminar in Germany, caused controversy in the wider Wing Chun community. What was supposed to be a training exercise became a fight between the two men. Boztepe allegedly gave Cheung no warning before switching from practice to real fight.[why?]
