Lucifer () is a 2007 South Korean television series starring Uhm Tae-woong, Ju Ji-hoon, and Shin Min-a. It aired on KBS2 from March 21 to May 24, 2007 on Wednesdays and Thursdays at 21:55 for 20 episodes.

The series is the second installment of the revenge trilogy by director Park Chan-hong and writer Kim Ji-woo, after Resurrection in 2005 and followed by Don't Look Back: The Legend of Orpheus in 2013.

Plot
A string of murders brings together a conflicted detective, a psychic librarian, and a mysterious lawyer with dubious motives. Detective Kang Oh-soo (Uhm Tae-woong) is assigned to two seemingly unrelated murder cases, where the only clues left behind are tarot cards, with the first card meaning "judgment." This leads him to Seo Hae-in (Shin Min-a), a quiet librarian who has the uncanny ability to make a psychic connection to an object to discover its history. She reveals to him that the victims were connected to the death of a high school boy years ago. The one common link between the suspects is their defense attorney, Oh Seung-ha (Ju Ji-hoon), a young lawyer who is seemingly kind and altruistic. Hae-in and Seung-ha later fall in love, though Oh-soo also has feelings for her.

As the culprit continues to leave clues, more lives are ruined and the body count rises. Oh-soo races to uncover the truth, but he is also haunted by the sins of his past which he has been trying to atone for. An incident in his youth 12 years ago has snowballed into a larger tragedy, and the two men involved are destined to face each other again, unsure who is good and who is evil.
