A shift range control device switches a shift range by controlling the drive of a motor. An angle calculation unit calculates a motor angle based on a motor rotation angle signal acquired from a motor rotation angle sensor detecting a rotational position of the motor. An acceleration calculation unit calculates a motor acceleration based on the motor angle. A moving average calculation unit calculates an acceleration moving average value as a moving average of at least one of a predetermined electrical angle cycle and a predetermined mechanical angle cycle of the motor acceleration. A drive control unit adopts the acceleration moving average value to control the drive of the motor such that the motor angle becomes a target motor angle value corresponding to a target shift range.
