A Bittersweet Life (Korean: 달콤한 인생; RR: Dalkomhan insaeng; lit. The Sweet Life) is a 2005 South Korean neo-noir action drama film written and directed by Kim Jee-woon. It stars Lee Byung-hun as Sun-woo, a hitman who becomes targeted by his boss after he spares the latter's cheating mistress.

The film was released theatrically in South Korea on 1 April 2005. It opened on 265 screens throughout the country, and registered a total of 1,112,950 admissions by the end of its run. It was also screened out of competition at the 2005 Cannes Film Festival.
