Leung Siu-lung, born in 1948 in Hong Kong, is an actor who has appeared in many Hong Kong martial arts movies. He often appeared billed as "Bruce Leung", "Bruce Liang", "Bruce Leong", or "Bruce Leung Siu-lung", and is thus generally grouped among the Bruce Lee clones that sprang up after Lee's death in the subgenre known as Bruceploitation. Leung learned martial arts from his father at the Cantonese opera. His major style is Goju Ryu Karate, he also is a Wing Chun practitioner.

Throughout the 1970s and 1980s, he appeared in a large number of martial arts films. Most familiar to Western audiences may be Jim Kelly's The Tattoo Connection (in which he only appeared briefly, but choreographed the action sequences) and Jackie Chan's Magnificent Bodyguards, which was the first Hong Kong film shot in 3D. He is also known for playing Bruce Lee in the notorious Bruceploitation classic, The Dragon Lives Again.

In addition, Leung appeared in his own star vehicles, including My Kung-Fu 12 Kicks, Kung Fu: The Invisible Fist, and Black Belt Karate.
