A floor reinforcement structure includes: a main floor; rear floor; side sill; a floor tunnel with a hat-like cross-section protruding from the floor and located medially in the main floor in the vehicle width direction and extending in a front-and-rear direction; and a vertical wall at the front of the rear floor extending in a vehicle vertical direction. The vertical wall is continuous with no steps The height of a top face thereof is larger than twice the height of a top face of the side sill, which is more than twice the height of a top face of a rear end portion of the floor tunnel.
