Into the Mirror (Korean: 거울 속으로; RR: Geoul sokeuro) is a 2003 South Korean supernatural horror film about a series of grisly deaths in a department store, all involving mirrors, and the troubled detective who investigates them.

After accidentally causing the death of his partner during a hostage situation, Wu Young-min quits the police force to work for his uncle as head security of Dreampia, an immense shopping center.

The re-opening was scheduled in a few days, until some strange murders begin to occur in the building.

The film explores the theory of dualism, doppelgangers and the Other through the visual medium of mirrors and reflections.

Derek Elley of Variety described Into the Mirror as an "Intermittently effective tale of a burned-out ex-cop who's drawn into a series of supernatural murders too often resorts to corny genre moments.
