Grim Fandango is a dark comedy neo-noir Windows adventure game released by LucasArts in 1998, primarily written by Tim Schafer. It is the first adventure game by LucasArts to use 3D computer graphics overlaid on pre-rendered, static backgrounds. As with other LucasArts adventure games, the player must converse with other characters and examine, collect, and use objects correctly to solve puzzles in order to progress.

Grim Fandango's world combines elements of the Aztec belief of afterlife with style aspects of film noir, including The Maltese Falcon, On the Waterfront and Casablanca, to create the Land of the Dead, through which recently departed souls, represented in the game as calaca-like figures, must travel before they reach their final destination, the Ninth Underworld. The story follows travel agent Manuel "Manny" Calavera as he attempts to save Mercedes "Meche" Colomar, a newly arrived but virtuous soul, during her long journey.

The game received positive reviews, praising its artistic design and overall game direction in particular. Grim Fandango was selected for several gaming awards at the time of release, and is often listed in publishers' lists of top games of all time. However, the game was considered a commercial failure and factored into LucasArts' termination of their adventure game development, contributing to the decline of the adventure game genre.
