A vehicle stability control device includes a yaw moment generation device and a control device. A variation yaw moment generated by simultaneous turn and acceleration/deceleration is expressed as a function of a longitudinal acceleration and a lateral acceleration. A longitudinal force and a lateral force of a tire have non-linear load dependency. The variation yaw moment when assuming that the load dependency is linear is a first variation yaw moment. The variation yaw moment considering the non-linear load dependency is a second variation yaw moment that is expressed as a product of the first variation yaw moment and a correction gain. In vehicle stability control, the control device controls the yaw moment generation device to generate a counter yaw moment counteracting the second variation yaw moment, based on the longitudinal acceleration, the lateral acceleration, and the correction gain.
