A vehicle pop-up hood device includes: a hinge base that is fixed to a vehicle body; a first arm that is pivotably connected to the hinge base; and a second arm that is fixed to a vehicle rear side end portion of a front hood and is pivotably connected to the first arm. Further, the vehicle pop-up hood device includes: an actuator that is provided between the first arm and the second arm, and that, by being operated, pivots the second arm with respect to the first arm; and a connecting portion that, at a time of completion of operation of the actuator, is set in an operating state in which the connecting portion restricts movement of the second arm with respect to the hinge base.
