Andrew Lau Wai-Keung (born 4 April 1960) is a Hong Kong film director, producer, and cinematographer.
 Lau began his career in the 1980s and 1990s, serving as a cinematographer to filmmakers such as Ringo Lam, Wong Jing and Wong Kar-wai.

 Apart from making films in his native Hong Kong, Lau has also made films in China, Korea and the United States.
 A highly prolific filmmaker, Lau has made films in a variety of genres, and is most notable in the West for his action and crime films which include the "Young and Dangerous" film series, the "Infernal Affairs" trilogy (the latter co-directed together with Alan Mak), and "Revenge of the Green Dragons" (executive produced by Martin Scorsese).
The Departed is a 2006 American crime drama film directed by Martin Scorsese and written by William Monahan.

Infernal Affairs is a 2002 Hong Kong crime-thriller film directed by Andrew Lau and Alan Mak.
 It tells the story of a police officer who infiltrates a triad, and a police officer secretly working for the same gang.
 The Chinese title means ""The Unceasing Path"", a reference to Avici, the lowest level of Hell in Buddhism, where one endures suffering incessantly.
 The English title is a word play, combining the law enforcement term "internal affairs" – typically the division of any law enforcement agency that would be responsible for (among other things) finding a mole – with the adjective "infernal", meant in this case as a reference not to fires or infernos in general, but specifically to the inferno of Hell ("Inferno" being the Italian word for "Hell").
 Thus, the English title is both a phonetic pun and – like the Chinese title – an allusion to a place or condition of eternal suffering.
 "Infernal Affairs" is the first in the Infernal Affairs series and was followed by "Infernal Affairs II" and "Infernal Affairs III".
Daisy () is a 2006 film directed by Hong Kong filmmaker Andrew Lau of the "Infernal Affairs" trilogy.
