The invention provides a vehicle bottom structure which can improve vehicle rigidity by means of a concise structure. The vehicle bottom structure (100) is characterized by comprising the components of a vehicle ground panel (108); a central channel (110) which projects to the upper part of the vehicle in the vehicle width direction of the ground panel (108); a lower beam (104) whihc extends in the front-and-back direction of the vehicle along an end in the vehicle width direction of the ground panel (108); a ground transverse beam (106a) which is is arranged on the lower beam (104) and the central channel (110) on the ground panel (108); and a ground longitudinal beam (116) which is configured below the ground panel (108), is superposed with the boundary of the lower beam (104) and the ground transverse beam (106a) in overlook and is relatively long in the front-and-back direction of the vehicle.
