In an autonomous driving vehicle information presentation apparatus, an outside information obtaining unit obtains outside information on an outside including a trailing vehicle present behind a host vehicle in a direction of advance. A determination unit determines presence of the trailing vehicle following the host vehicle, based on the outside information. A calculation unit 325 calculates a host vehicle-trailing vehicle distance being a distance between the host vehicle and the trailing vehicle when the determination unit determines that the trailing vehicle following the host vehicle is present. An information presentation unit presents information addressed to the trailing vehicle by using a rear display unit provided in a rear portion of a cabin of the host vehicle. The information presentation unit sets a presented state of the information addressed to the trailing vehicle according to a magnitude of the host vehicle-trailing vehicle distance calculated by the calculation unit.
