The present disclosure may provide a shift range control apparatus that controls on-off operations of switching elements in a driver circuit, drives a motor, and switches a shift range. The shift range control apparatus may be configured to determine an abnormality of a rotation angle sensor detecting a rotation angle of the motor, to control a drive of the motor using a detection value, and to execute a control which switches an energization phase every energization phase switching period without using the detection value of the rotation angle sensor in response to that the rotation angle sensor is abnormal.
