Scythe is a board game for one to five players designed by Jamey Stegmaier and published by Stonemaier Games in 2016. Set in an alternative history version of 1920s Europe, players control factions that produce resources, develop economic infrastructure, and use dieselpunk combat mechs to engage in combat and control territories. Players take up to two actions per turn using individual player boards, and the game proceeds until one player has earned six achievements. At this point, the players receive coins for the achievements they have attained and the territories they control, and the player with the most coins is declared the winner.

Dieselpunk is a retrofuturistic subgenre of science fiction similar to steampunk or cyberpunk that combines the aesthetics of the diesel-based technology of the interwar period through to the 1950s with retro-futuristic technology and postmodern sensibilities. Coined in 2001 by game designer Lewis Pollak to describe his tabletop role-playing game Children of the Sun, the term has since been applied to a variety of visual art, music, motion pictures, fiction, and engineering.
