Dicky Cheung Wai-kin (Chinese: 張衛健; born 8 February 1965) is a Hong Kong actor and singer.

However, the following eight years he only acted in small parts until 1991 when he finally got the chance to be the main actor in the TVB drama called "Laoyou Guigui"("A Step Beyond").

A sequel to the TV adaptation was planned, but due to a contract dispute with TVB, Cheung left before production began.

Cheung's most notable performance that made him famous was his portrayal of the Monkey King in the 1996 TVB adaptation of the classic Chinese tale Journey to the West.

In 1999, TVB's rival station ATV acquired the Hong Kong broadcasting rights to his Taiwanese television series Young Hero Fong Sai Yuk.

The show was an instant hit in Hong Kong and managed to gain much higher ratings than TVB's own television series.

The TVB series showing at that time was Dragon Love, starring Benny Chan Ho Man, who replaced Cheung in the Journey to the West sequel, In one of the TV adaptations of Louis Cha's Wuxia novel The Deer and the Cauldron.

Cheung played the anti-hero Wai Siu-Bo, a character previously portrayed by Tony Leung Chiu-Wai, Stephen Chow and Jordan Chan in many television and film adaptations, in The Duke of Mount Deer.

He starred in TVB's 50th anniversary drama, The Learning Curve of a Warlord <大帥哥>, which was produced by Steven Tsui.
