English: Gaelic handball (known in Ireland simply as handball; ) is a sport similar to Basque pelota, racquetball, squash and American handball (an almost identical game). It is one of the four Gaelic games organised by the Gaelic Athletic Association. The game may be played with two (singles) or four players (doubles). An important difference between it and racquetball or squash is that the players hit the ball with the hand instead of a racquet. Either the left and right hand can be used, depending on where the ball is hit.
