A gear shifting control system for a vehicle includes an engine, a continuously-variable transmission, and an electronic control unit. The vehicle includes driving wheels. The engine includes an electronic throttle valve controlling a torque of the engine. The continuously-variable transmission is disposed in a power transmission path between the engine and the driving wheels. The electronic control unit is configured to i) decrease the torque of the engine by decreasing a throttle opening of the electronic throttle valve when the continuously-variable transmission upshifts, and ii) output a gear shifting start command for starting the upshifting of the continuously-variable transmission with a delay relative to a decrease start command for starting the decrease of the throttle opening of the electronic throttle valve when the continuously-variable transmission upshifts.
