Warhammer is a tabletop miniature wargame with a medieval fantasy theme. The game was created by Bryan Ansell, Richard Halliwell, and Rick Priestley, and first published by the Games Workshop company in 1983.

Miniature wargaming is a form of wargaming in which military units are represented by miniature physical models on a model battlefield. The use of physical models to represent military units is in contrast to other tabletop wargames that use abstract pieces such as counters or blocks, or computer wargames which use virtual models. The primary benefit of using models is aesthetics, though in certain wargames the size and shape of the models can have practical consequences on how the match plays out.
