This vehicle floor structure comprises: a tunnel part (2); a front floor (3); a kick-up part (5); a rear floor (4); and a pair of lower-section reinforcement members (6). The tunnel part (2) is disposed in the center, along the direction of travel of a vehicle. The front floor (3) spreads to both sides of the tunnel part (2). The kick-up part (5) is formed contiguously with the rear end of the tunnel part (2) and the front floor (3). The lower-section reinforcement members (6) are joined to the bottom surface of a continuous section connecting the tunnel part (2) to the front floor (3). These lower-section reinforcement members (6) are disposed so as to approach each other in the vehicle width direction moving toward the kick-up part (5).
