A vehicle localization system includes: an electronic control unit estimating a vehicle position including a longitudinal position on a map in an extension direction of a road on which the vehicle is traveling and a lateral position on the map in a lateral direction of the road; and a storage device storing a map database including map information. The electronic control unit obtains a vehicle speed and a pitch angle of the vehicle, perceives a measured position of the vehicle on the map based on a measurement result of a positioning device mounted on the vehicle and the vehicle speed, and estimates the longitudinal position from comparison between a rate of change in pitch angle of the vehicle along the road and a rate of change in height on the map along the road, based on the measured position, the map information, and the pitch angle.
