Royal Tramp is a 1992 Hong Kong wuxia comedy film based on Louis Cha Leung-yung (查良鏞)'s novel The Deer and the Cauldron. Directed by Wong Jing ( 王晶), the film was one of the five top grossing Hong Kong films in 1992; Stephen Chow Sing-chi (周星馳), who played the protagonist Wai Siu-bo, also starred in the other four of those films. The film was followed by a sequel, Royal Tramp II, in the same year.

The story of Wai Siu-bo, a pimp who after saving Chan Kan-nam (劉松仁 Damian Lau Chung-yan), the leader of the Heaven and Earth society, a revolutionary group, is made a member. After a botched first assignment for the group, he is made a servant to the young Emperor, the very person the Heaven and Earth society want to overthrow. What follows is plenty of mayhem and laughter.
