Provided are a motor driving control apparatus and a steering system. The motor driving control apparatus includes an inverter circuit configured to supply a motor driving power to a motor for steering assist, a motor control circuit configured to control operation of the inverter circuit according to whether a control power is input, and a switch circuit configured to control whether to input the control power to the motor control circuit in response to a control signal. When a failure occurs inside or outside the steering system, the apparatus and steering system can immediately stop motor driving for steering assist and thereby prevent a vehicle accident.
