Alone in the Dark is a survival horror video game designed by Frédérick Raynal and developed and published by Infogrames for the PC. Alone in the Dark was released for MS-DOS in 1992, ported for the 3DO by Krisalis in 1994, and ported for iOS by Atari in 2014. Set in 1920s Louisiana, the game challenges the player to guide the player character out of a haunted mansion, advancing by solving puzzles while either banishing, slaying, or eluding various ghosts and monsters. The player can collect and use weapons, manage a weight-based inventory system, and explore a partially nonlinear map.

Alone in the Dark received critical acclaim upon its release, and is considered a breakthrough and influential title, as it was the first 3D survival horror game. Among the accolades which followed its release, Alone in the Dark received the European Computer Trade Show awards for Best Graphics and Most Original Game in 1993. In 2009, Empire included Alone in the Dark on their list of 100 greatest video games of all time.

Alone in the Dark is considered a forefather of the survival horror genre, and its influence can be seen in the Resident Evil franchise. Alone in the Dark has also spawned four follow-up games as part of the series, as well as two films loosely based on them.
