To provide light distribution control technology for a vehicle lamp capable of improving driver visibility.A vehicle lamp control apparatus that controls light irradiation state of a vehicle lamp capable of irradiating light forward of a vehicle, where the light irradiation state is controlled such that, when a vehicle speed is lower than a reference value, a road surface illuminance due to light from the vehicle lamp at a first forward distance which is close to the vehicle becomes a first value; when the vehicle speed is greater than the reference value, the road surface illuminance due to light from the vehicle lamp at the first forward distance becomes a second value which is smaller than the first value; and the road surface illuminance due to light from the vehicle lamp at a second forward distance which is far from the vehicle becomes substantially constant regardless of the vehicle speed.
