Andrew Lau Wai-keung (Chinese: 劉偉強, born 4 April 1960) is a Hong Kong film director, producer, and cinematographer.

As a child and high school student, Lau admits to not liking Hong Kong, since it was a British colony.

[2] He later served as a cinematographer for Sammo Hung's 1986 martial arts film Millionaire's Express and Ringo Lam's 1987 crime thriller City on Fire, where he became known for his use of lighting and hand-held cinematography.

His work on As Tears Go By (1988), the directorial debut of Wong Kar-wai, earned him his first Hong Kong Film Award nomination for Best Cinematography.

He also shot the beginning portion of Wong Kar-wai's Chungking Express in 1994 (Christopher Doyle was cinematographer for the film's second half).

In 2014, Lau directed an American action crime drama film Revenge of the Green Dragons, which was co-directed by Andrew Loo and executive produced by Martin Scorsese.

[5] Lau's short film was centered on Beijing cuisine, and consisted of actors from China, Hong Kong and Taiwan serving as "ambassadors".

The cast included Tony Leung Chiu-Wai, Shu Qi, and Jay Chou, actors who had appeared in several of Lau's films.
