The 11th Hour is a 1995 puzzle computer game with a horror setting. It is the sequel to the 1993 game The 7th Guest. It was developed by Trilobyte and used a later version of the "Groovie" graphic engine than that used by The 7th Guest. Like its predecessor game, The 11th Hour features the music of George "The Fat Man" Sanger and Team Fat.

The 11th Hour was very late to market and failed to meet sales expectations upon its release. Also, at the time, Microsoft Windows had become the standard gaming platform for PCs; however, the first release of the game was made specifically for MS-DOS, resulting in many customers being unable to play it properly. Early into its development, a port to the 3DO was planned, but this was ultimately cancelled.
