A vibration damping control apparatus which has a control unit that calculate a pitch damping driving torque based on a pitch angular velocity of a vehicle body, and control an engine based on at least the pitch damping driving torque. The control unit stores a vehicle speed corresponding to a phase difference of −180° in a relationship between a phase difference and a vehicle speed as an upper limit reference vehicle speed, the relationship being derived by obtaining phase characteristic of a wheelbase filter function for various vehicle speeds and obtaining a relationship between the phase difference of vertical displacements of the vehicle body at positions of front and rear wheels and a vehicle speed with respect to a pitch resonance frequency of the vehicle, and reduces the pitch damping driving torque when a vehicle speed is not higher than the upper limit reference vehicle speed.
