Danish Longball (sometimes called Swedish longball) is a bat-and-ball game founded in Denmark. It is popular in British secondary schools, and is played recreationally by scouts, the Air Training Corps and by the British Navy and Australian Navy. It is also a popular sport at U.S. summer camps.

To English-speakers Danish Longball may be described as a hybrid of baseball and cricket, in which each team takes turns batting and fielding. In British secondary schools in particular, an element of dodgeball is incorporated, with a player being "out" if he is hit with the ball (outside of the safety zone) below the head whilst aiming to get a run. there is a variant where it is more like a cross of football, cricket and dodgeball, but it is less common.

The batting field has two parts: Inside and outside a square (or circle). Fielders can position themselves inside or outside of the square.The fielder who fields the ball cannot move with it rather they must pass it to another fielder in a better position to hit the runner.
