The "sidelines" are the white or colored lines which mark the outer boundaries of a sports field, running parallel to each other and perpendicular to the goal lines.[1] The sidelines are also where the coaching staff and players out of play operate during a game. The area outside the sidelines is said to be out of bounds. The term is predominantly in use in American football, Canadian football, field lacrosse and basketball.

In rugby union, rugby league and association football, they are known as touch-lines. The foul line is a similar concept in baseball. In cricket, the boundary lines can be marked by a rope. Sports in which the playing surface is bounded by walls, such as ice hockey, box lacrosse, and indoor football, do not use sidelines; in these sports, coaches and reserve players are positioned in recessed benches behind the walls.
