Flames of War is a World War II and Cold War tabletop miniatures wargame produced by the New Zealand company Battlefront Miniatures Ltd. Flames of War allows players to wargame company level battles using 1/100 scale miniatures (15mm).

Gameplay takes place over a series of turns, with players alternating movement, shooting and close assault. This simple sequence of play, often called "I-Go, You-go", helps people who are unfamiliar with wargames or who are familiar with other games with a similar structure, such as Warhammer Fantasy Battles or Warhammer 40,000, to quickly learn the rules. The game is optimised for two players, although it can be played by a larger number of players grouped in teams.

Play revolves around company-level tactics, with each stand or element representing an infantry fire team (half-squad/section), an artillery piece and its crew, or a single vehicle (such as a tank, jeep, or armoured car). Air support is also available, in the form of fighters and light bombers, to players wishing to use it, with aircraft generally being represented by 1:144 scale models.
