A lower vehicle-body structure allows miniaturization of an undercover and prevents an increase in minimum ground clearance. In the lower vehicle-body structure, a vehicle body floor includes step-up portions connected to a floor tunnel on opposite sides of the floor tunnel in a vehicle width direction at least in regions where first and second cross members are disposed on the vehicle body floor. The lower vehicle-body structure includes a mount member that faces the floor tunnel and connects the step-up portions on the opposite sides of the floor tunnel, and includes first and second undercovers that cover a lower side of the mount member so as to be continuous with a bottom surface of the vehicle body floor on outer sides of the step-up portions in the vehicle width direction.
