A headlamp control device estimates, in a case where an ambient illuminance of a subject vehicle is equal to or lower than a predetermined switching illuminance when a state of a headlamp is the ON state, a time required for the subject vehicle to travel to an entrance of a tunnel in front of the subject vehicle, as a first time, switches, in a case where the first time is longer than a first determination time, the headlamp state from a low-beam state to a high-beam state, and, keeps, in a case where the first time is equal to or shorter than the first determination time, the headlamp state as the low-beam state.
