A steering return control apparatus of MDPS may include: a column torque sensor configured to sense a column torque of a steering wheel; a steering angle sensor configured to measure a steering angle of the steering wheel; a column velocity calculator configured to calculate a column velocity at which a steering column is rotated; a vehicle velocity sensor configured to sense a vehicle velocity; a lateral acceleration sensor configured to sense a lateral acceleration of the vehicle; and a damping controller configured to detect a damping compensation gain in an on-center region according to at least one of the column torque, the column velocity and the lateral acceleration, and applies the damping compensation gain to a default damping amount, when the steering angle falls within the on-center region while at least one of the column torque, the column velocity and the vehicle velocity satisfies a preset damping compensation condition.
