Stephen Chow Sing-Chi, born 22 June 1962, is a scriptwriter, film director and actor in many blockbuster movies in Hong Kong.

Chow is considered the finest Hong Kong screen comedian since Michael Hui, and a mega-superstar to all concerned in the Hong Kong entertainment circle, epitomized by his nickname 星爺 (Sing Yeh, lit. Grandmaster Sing). However, his brand of mo lei tau comedy, which includes puns, double entendre and poking fun at Chinese culture, meant that few of his earlier films could exercise much impact in the West until his later films, Shaolin Soccer (2001) and Kung Fu Hustle (2004).
