A damping force control apparatus with adjustable shock absorbers is disclosed. An electronic control unit calculates estimated roll angle and estimated pitch angle of a vehicle body based on detected sprung accelerations, calculates a target pitch angle from the estimated roll angle, and determines target damping force required for front-wheel-side shock absorbers such that the stimulated pitch angle coincides with the target pitch angle; calculates rear-wheel-side jack-up force exerted on the rear-wheel-side vehicle body based on detected vehicle speed detected yaw rate and detected lateral acceleration, and determines the force in the direction for overcoming the calculated jack-up force as target damping force of rear-wheel-side shock absorbers; and controls the operation of each actuator based on the rear-wheel-side and front-wheel-side target damping forces.
