The Wargames Research Group (WRG) is a British publisher of rules and reference material for miniature wargaming. Founded in 1969 they were the premier publisher of tabletop rules during the seventies and eighties, publishing rules for periods ranging from ancient times to modern armoured warfare, and reference books which are still considered standard works for amateur researchers and wargamers. They are best known for their seminal ancient and medieval period rules, and also for De Bellis Antiquitatis and Hordes of the Things fantasy rules.
