A headlight controller controls a headlight unit that sends out illumination light frontward of a vehicle. The headlight controller includes an inter-vehicle distance obtainer, a light distribution controller, and an illumination controller. The inter-vehicle distance obtainer acquires an inter-vehicle distance from the vehicle to a vehicle in front traveling in front of the vehicle. The light distribution controller partially dims or shades a range corresponding to a position of the vehicle in front. When the inter-vehicle distance is less than a first distance, the illumination controller reduces at least an amount of illumination light in an illumination range of a low beam out of the illumination range of the low beam and an illumination range of a high beam by the headlight unit, regardless of operation of the light distribution controller.
