An opening/closing control device for a shutter of a vehicle is provided which is capable of appropriately opening and closing the shutter according to the traveling conditions of the vehicle, and improving fuel economy while maintaining excellent maneuverability of the vehicle. When the detected vehicle speed VP is not smaller than a predetermined first reference value VREF1 and smaller than a second reference value VREF2, the shutter 47 is closed (steps 3, 5, 6 in FIG. 4 ) to improve fuel economy. On the other hand, when the vehicle speed VP is not smaller than the second reference value VREF2, the shutter 47 is opened (steps 5, 8 in FIG. 4 ). Further, at this time, a condition for opening the shutter 47 is set according to at least one of a grip force FG of the vehicle V and a steering angle ¸ STR (steps 2, 7 in FIG. 4 ). This maintains excellent maneuverability of the vehicle V.
