A road surface water depth calculation device includes: an acquisition unit configured to acquire flooding locations at which a vehicle travels and water depth candidates of the flooding locations; an extraction unit configured to extract a plurality of continuous flooding locations from the acquired flooding locations; an altitude acquisition unit configured to acquire altitudes of the extracted flooding locations; an estimation unit configured to calculate a sum of the water depth candidate and the altitude, acquired by the altitude acquisition unit, of each of the extracted flooding locations, and estimate the sum as a water surface altitude which is an altitude of a water surface of each of the extracted flooding locations; and a calculation unit configured to calculate a water depth of the extracted flooding location based on the water surface altitude and the altitude, acquired by the altitude acquisition unit, of each of the extracted flooding locations.
