The Virtual Theatre is a computer game engine designed by Revolution Software to produce adventure games for computer platforms. The engine allowed their team to script events, and move animated sprites against a drawn background with moving elements using a point-and-click style interface. Upon its first release, it rivaled competing engines like LucasArts' SCUMM and Sierra's Creative Interpreter, due to its then high level of artificial intelligence. The engine was first proposed in 1989, while the first game to use it, Lure of the Temptress, was released in 1992, followed by Beneath a Steel Sky (1994), Broken Sword: The Shadow of the Templars (1996) and Broken Sword II: The Smoking Mirror (1997).

It allowed in-game characters to wander around the gameworld independently of each other, performing "everyday life" actions, which was not previously possible, and all characters and objects occupied space; consequently, non-player characters had to side-step the player's protagonist and any other object they came across, as well as the player having to side-step them, achieving a more realistic game world that previous engines were unable to provide, though non-player characters could unwittingly block a path as the player was traversing the game scene. Non-player characters performed much simpler tasks with each release due to size constraints.

Two games (Broken Sword: The Shadow of the Templars and Broken Sword II: The Smoking Mirror) that use a Virtual Theatre variant engine can now be played on modern hardware using ScummVM, which as a result allows the engine to run on platforms where the titles were not officially released. In 2012, it was confirmed that the engine would be revived as "Virtual Theatre 7" for the fifth Broken Sword titled Broken Sword: The Serpent's Curse (2013).
