An electric power steering apparatus according to the present invention includes a first control device that is capable of controlling a first actuator of a steering device, a second control device that is capable of controlling a second actuator of the steering device, and a third control device that is capable of switching connection to, and disconnection from, at least one of the first actuator and the second actuator. When a failure occurs in the first control device, the first control device is disconnected from the first actuator, and the third control device is connected to the first actuator. When a failure occurs in the second control device, the second control device is disconnected from the second actuator, and the third control device is connected to the second actuator. In this way, even when a failure occurs in one of a plurality of control devices, reduction in total output of electric motors can be prevented.
