The 7th Guest is an interactive movie puzzle adventure game, produced by Trilobyte and originally released by Virgin Interactive Entertainment in April 1993. It is one of the first computer video games to be released only on CD-ROM. The 7th Guest is a horror story told from the unfolding perspective of the player, as an amnesiac. The game received press attention for making live action video clips a core part of its gameplay, for its then-unprecedented amount of pre-rendered 3D graphics, and for its adult content. The game was very successful, with over two million copies sold. The game alongside Myst, is widely regarded as a killer app that accelerated the sales of CD-ROM drives. The 7th Guest has subsequently been re-released on Apple's app store for various systems such as the Mac. Bill Gates called The 7th Guest "the new standard in interactive entertainment".

An adventure game is a video game genre in which the player assumes the role of a protagonist in an interactive story, driven by exploration and/or puzzle-solving. The genre's focus on story allows it to draw heavily from other narrative-based media, such as literature and film, encompassing a wide variety of genres. Most adventure games are designed for a single player, since the emphasis on story and character makes multiplayer design difficult. Colossal Cave Adventure is identified by Rick Adams as the first such adventure game, first released in 1976, while other notable adventure game series include Zork, King's Quest, Monkey Island, Syberia, and Myst.
