A damping force control device for controlling damping forces of shock absorbers by a control device, which is configured to extract first vibration components in a first frequency range and second vibration components in a higher frequency range than the first frequency range from vertical accelerations of a sprung mass at the positions of wheels, to calculate correction coefficients which decrease as the degree of the second vibration increases with respect to the degree of the first vibration, and to control damping coefficients of the shock absorbers so as to be the products of target damping forces calculated based on the vertical accelerations of the sprung mass and the correction coefficients.
