The present invention discloses a center floor vehicle body structure. According to an embodiment of the present invention, the center floor vehicle body structure may include: i) a pair of upper panels configured to be attached to each other while a tunnel portion is placed therebetween along a front, rear, and longitudinal direction of the center flower panel, on an upper surface of a connection portion connecting a dash panel to a center floor panel and of a center floor panel, and configure to be made by performing a hot stamping process on tailor welded blanks (TWB) to which heterogeneous steel plates are attached; and ii) a pair of reinforcement panels arranged in a horizontal direction of a center floor panel, and having a part thereof attached to an upper surface of the upper panel and the remaining part thereof attached to the center floor panel. Accordingly, the present invention is able to prevent a welded portion of an upper center floor member, to which a TWB hot-stamping technique is applied, from being broken by collision energy.
