Kenneth Tsang Kong (5 October 1935 – 27 April 2022) was a Hong Kong actor. Tsang's career spanned 50 years and included a variety of acting roles. Tsang won the Best Supporting Actor Award at the 34th Hong Kong Film Awards in 2015. Tsang was born in Hong Kong with family roots in Zhongshan, Guangdong. He attended high school in Texas, U.S. and received a degree in architecture from the University of California, Berkeley. He returned to Hong Kong in the early 1960s but was bored by the work. His older sister, Jeanette Lin Tsui  was a film star at the time and provided Tsang with several connections in the industry which boosted his acting career. In the media, Lin Tsui was always presented as Tsang's younger sister instead as it was moreover uncommon for female stars to reveal their age.

Tsang's film debut was in the movie The Feud (1955), when he was just 16, which was followed by a role in Who Isn't Romantic? (1956). In the mid 1960s, Tsang starred in detective films and classic kung fu movies with (at the time) Hong Kong teen idols Connie Chan Po-chu and Josephine Siao. Tsang also appeared in a few Wong Fei-Hung movies in the late 1960s. In the 1986, Tsang worked as taxi cab owner, Ken, in John Woo's A Better Tomorrow. Subsequent collaborations with Woo included the role of Ken in A Better Tomorrow 2 in 1987, police officer Danny Lee's murdered partner in The Killer in 1989, and the strict adoptive father of Chow Yun-fat, Leslie Cheung and Cherie Chung in Once a Thief in 1991.
