Abstract: There are provided a vehicle orientation estimation system and a vehicle orientation estimation method which can accurately estimate an inclination angle of a vehicle without being affected by a traveling place or an environment in a vehicle orientation estimation system and a vehicle orientation estimation method which estimate an orientation of the vehicle using an in-vehicle camera. A region setting unit that sets a first region and a second region that is on the same horizontal line as the first region, in a measurement region corresponding to a road surface acquired by a distance measurement device mounted on a vehicle; a distance calculation unit that calculates a distance to the road surface of each of the first region and the second region from the vehicle; and an inclination angle calculation unit that obtains an inclination angle of the vehicle based on the distance to the road surface of each of the first region and the second region and a positional relationship of the first region and the second region are included.
