Fulltime Killer (Chinese: 全職殺手) is a 2001 Hong Kong action film produced and directed by Johnnie To, and also written, produced and directed by Wai Ka-fai, and also produced by and starring Andy Lau. The film was released on 3 August 2001.

The film is based on Pang Ho-cheung's novel of the same name.

Based on a book by Hong Kong filmmaker Pang Ho-cheung, Fulltime Killer protagonist O is a hitman being challenged by new hotshot Lok Tok-wah. O has lived a life of seclusion as the number one hitman in Asia. The woman living at his contact address is captured after O foils a set-up by his boss. He then goes on the run while trying to fend off his adversary. The last part of the movie focuses on an Interpol detective's attempt to write the story of Tok and O.

The film has two endings. The normal one that appeared in theaters and the special ending for Malaysia where O and Chin end up being caught by police. This was supposedly done as per special request to show that "Crime doesn't pay".^{[citation needed][3]}
