A vehicle floor structure includes a floor member having an opening and a floor panel covering the opening. The floor panel is configured by sequentially arranging and integrating a plurality of kinds of unit panels in a lateral direction of the unit panels, the unit panels having rectangular shapes as viewed from above a vehicle. Two end sides of the floor panel extending along a direction in which the unit panels are arranged (x direction) and one side of at least one of two unit panels arranged at opposite ends of the floor panel are supported by support portions of a floor member.
