An object identification device includes: a region determination unit that acquires observed position information indicating positions at which an object is observed, and determines whether each position is in any one of regions into which an area indicated is divided; a road reference position conversion unit that converts each position in the region, into a traveling direction position parallel to an assumed road direction and a transverse direction position perpendicular to the assumed road direction; and a comparison unit that rearranges the positions in order of the traveling direction, creates pairs of front and rear positions, calculates a difference in the traveling direction positions and the transverse direction positions between each pair of positions, and determines that a pair of positions between which the differences are within thresholds specified in respective items are derived from the same object, and a pair of positions between which at least one of the differences is greater than the threshold are derived from different objects.
