The present disclosure relates to an apparatus and method for protecting a battery pack, and the technical object to be achieved is to provide an apparatus and method for protecting a battery pack in which, when a vehicle is started, the ignition of the vehicle may be stably turned off in response to a failure of a battery pack and a relay, and passengers and the vehicle may be protected from accidents. To this end, the apparatus of the present disclosure includes a battery module, a relay configured to allow an output of the battery module to be applied as a load of a vehicle or block the output of the battery module, an actuator operated by power supplied from a starter battery, and a processor configured to, when a start signal is input, monitor the battery module and detect a failure of the relay, and when the relay fails, control the actuator to operate to discharge the starter battery and block a start of the vehicle.
