Flag football is a variation of American football (Gridiron), primarily played for recreational and amateur purposes. Unlike traditional tackle football, where players tackle opponents to stop their progress, flag football involves players wearing belts with flags attached to them.

The objective of the game remains the same: to advance the ball down the field and score touchdowns by crossing the opponent's goal line.

In flag football, instead of tackling, defenders must remove one or both of the ball carrier's flags to "tackle" them. Once a flag is removed, the play is considered dead at that spot. Flag football is typically played with fewer players on each team compared to tackle football, often with smaller fields and shorter game durations.

Flag football is popular for its reduced risk of injury compared to tackle football, making it suitable for players of all ages and skill levels. It can be played recreationally in parks, schoolyards, and organised leagues, as well as competitively in tournaments and leagues at various levels of competition. Additionally, flag football is often used as a training tool for aspiring football players to develop skills such as passing, catching, and strategy in a less physically demanding environment.
