A motorcycle cowl structure for suppressing a flow of air flowing toward a rider and a pillion passenger when the rider travels alone or when a pillion passenger is mounted on the same vehicle. A flow of air flowing toward a rider sitting on a rider seat and a pillion passenger sitting on a pillion passenger seat is suppressed by the cowl structure that includes left and right cowl main body portions for preventing the flow of air from hitting the knee portions, thighs, waist and flanks of the rider. Left and right movable cowl portions are provided on the respective left and right cowl main body portions so as to be movable vehicle-widthwise and opened to prevent flow of air from hitting the pillion passenger. The opening and closing of the movable cowl portions can suppress flow of air flowing toward the rider and the pillion passenger.
