Button Men Wiki is a community-maintained reference site dedicated to the dice game Button Men, designed by James Ernest and published by Cheapass Games in 1999. The game originally featured character designs on pinback buttons, typically sold in themed sets of two without dice; hundreds of buttons were later released by Cheapass Games and other companies. A new edition released in 2018 used cards to represent characters.

The wiki aims to preserve and organize information about the game, including material that has become difficult to find. Its guides cover the basic rules, fighters (called Buttons), dice and their abilities, strategy, skills, and variable or “Swing” dice. It also gathers miscellaneous resources, such as web links and references to Button Men in other media. Players can use the site to explore the game and find information relevant to playing online through the fan-maintained Buttonweavers site.

The project welcomes community contributions, including article cleanup, new pages, categories, and scans of buttons.
