Sympathy for Mr. Vengeance (Korean: 복수는 나의 것; lit. "Vengeance Is Mine") is a 2002 South Korean neo-noir crime thriller film directed by Park Chan-wook, who co-wrote the script with Lee Jae-soon, Lee Moo-young, and Lee Yong-jong. Starring Song Kang-ho, Shin Ha-kyun, and Bae Doona, the film follows an ill-fated kidnapping of a wealthy man's daughter, leading to a path of vengeance.

Sympathy for Mr. Vengeance did not fare well commercially upon its initial release in South Korea and garnered mixed reviews. Despite this, it won several awards. It is the first installment in director Park's thematic Vengeance Trilogy, and is followed by Oldboy (2003) and Lady Vengeance (2005).
