Softporn Adventure is a comedic, adult-oriented text adventure game produced for the Apple II in 1981. The game was created by Charles Benton and released by On-Line Systems, later renamed Sierra On-Line. Years later, Softporn Adventure was remade and expanded as Leisure Suit Larry series of adult-oriented video games, and the first entry in that series, 1987's Leisure Suit Larry in the Land of the Lounge Lizards, was a nearly direct graphical adaptation of Softporn Adventure. Another graphical version was released as Las Vegas for various Japanese computers in 1986 by Starcraft.

In the game, the player (playing a down-on-his-luck party animal) searches for certain items that will allow him to win the affections of three beautiful (and sometimes not-so-beautiful) women. Benton claimed that parts of the game were based on his own life, but did not specify which ones.
