A shift range control device switches a shift range by controlling drive of a motor. An angle calculation unit calculates a motor angle based on a signal from a rotation angle sensor that detects a rotation position of the motor. A drive control unit drives the motor so that the motor angle becomes a target angle according to the target shift range, and stops a rotor by a fixed phase energization, when the motor angle reaches a target angle. When the rotor vibrates with respect to stop position, the drive control unit maintains a state in which a brake torque, which is the torque generated when moving away from center of vibration, is larger than an acceleration torque, which is the torque generated when moving toward the center of vibration, and reduces the current that energizes the motor based on a difference between the brake torque and the acceleration torque.
