A roll vibration damping control system (10) includes an electronic control unit (30) configured to: compute a sum of a product of a roll moment of inertia (Ix) and a roll angular acceleration (φs2) of a vehicle body (16), a product of a roll damping coefficient (Cx) and a first-order integral (φs) of the roll angular acceleration, and a product of an equivalent roll stiffness (Kx') of the vehicle and a second-order integral (φ) of the roll angular acceleration, as a controlled roll moment (Mxc) to be applied to the vehicle body; compute a roll moment around a center of gravity of a sprung mass as a correction roll moment (Mxa), the roll moment being generated by lateral force on wheels due to roll motion; and compute a target roll moment (Mxt) based on a value obtained by correcting the controlled roll moment with the correction roll moment.
