Fall Guys (formerly known as Fall Guys: Ultimate Knockout) is a free-to-play platform battle royale game developed by Mediatonic and published by Epic Games. The standard "Classic" and "Knockout" modes involve up to 32 players who control bean-shaped characters and compete against each other in a series of randomly selected mini-games such as obstacle courses and survival challenges. Players are eliminated as the rounds progress until, eventually, the last remaining player or team is crowned the winner. There are also many other modes, such as Explore, with different game rules and player counts. The game draws inspiration from game shows like Takeshi's Castle, It's a Knockout, Wipeout, and playground games like tag and British Bulldog.

The game was released by Devolver Digital for PlayStation 4 and Windows on 4 August 2020. Following their acquisition of Mediatonic, the publishing rights were transferred to Epic Games. Subsequently, the game was made free-to-play on 21 June 2022 and released on additional platforms including Nintendo Switch, PlayStation 5, Xbox One and Xbox Series X/S, with full cross-platform play support among all platforms. As part of the transition, the game adopted a paid battle pass system for its monetization, with a new "Show-Bucks" premium currency - comparable to the way that Fortnite's V-Bucks work, and with the same pricing. On 16 August 2024 the game was released on mobile via the Epic Games Store, worldwide on Android and only in the European Union on iOS.

Fall Guys received positive reviews from critics for its chaotic gameplay and visual appearance. The game was a commercial success, selling more than 10 million copies and attracting more than 50 million players after the game went free-to-play. Since launching in 2020, Mediatonic has continued to release consistent updates containing new features, cosmetics and levels.
