The purpose of the present invention is to provide a vehicle drive device capable of efficiently driving a vehicle using in-wheel motors without falling into the spiral of enhancing motor drive at the cost of increased vehicle weight. The present invention provides a vehicle drive device for driving a vehicle using in-wheel motors, characterized by comprising in-wheel motors (20) that are disposed in wheels (2b) of the vehicle (1) and drive the wheels; a vehicle-body-side motor (16) that is disposed in the body of the vehicle and drives the wheels; and a controller (24) that controls the in-wheel motors and the vehicle-body-side motor on the basis of the output required by a driver, wherein the controller allows the vehicle-body-side motor and not the in-wheel motors to generate drive power when the output required by the driver is less than a predetermined output, and furthermore, the controller allows the vehicle-body-side motor and the in-wheel motors to generate drive power when the output required by the driver is equal to or greater than the predetermined output.
