A steering return control apparatus of an MDPS may include: a vehicle speed sensor configured to detect a vehicle speed; a yaw rate sensor configured to sense a tilted state of the vehicle, and output a yaw rate value; a column torque sensor configured to detect a column torque applied to a steering shaft; a motor encoder configured to detect a rotation amount of a motor; and a return controller configured to receive the vehicle speed, the yaw rate value and the column torque, determine whether the vehicle is driven in a neutral state, calculate a rack position and rack speed from the rotation amount of the motor, set a target position value in the neutral drive state, calculate a return torque for returning a steering wheel to the target position value, adjust a gain according to the vehicle speed and column torque, and output a return torque driving value.
