A shift range control device switches a shift range by controlling a drive of a motor in which a rotor rotates by energizing a motor winding. An angle calculation unit calculates a motor angle based on a signal from a rotation angle sensor that detects a rotation position of the rotor. An energization control unit drives the rotor so that the motor angle becomes a target angle according to the target shift range, and stops the rotor at a position where the motor angle becomes the target angle, by controlling the energization of the motor winding. A zero point estimation unit estimates a speed 0 point, which is a timing at which a rotational speed of the vibrating rotor becomes 0 during the stop control for stopping the rotor. The energization control unit switches a current control at the estimated speed 0 point.
