To provide a vehicle body lateral structure capable of attaining efficiency of energy due to a lightweight vehicle body and improvement in traffic safety due to ensured rigidity of the vehicle body.SOLUTION: A vehicle body lateral structure S of the present invention includes a floor cross member 2 being connected to a side sill 1 and extending in a vehicle width direction, and a bulkhead 3 that divides a closed cross section of the side sill 1 in a vehicle body fore-and-aft direction laterally in the vehicle width direction to the floor cross member 2. The bulkhead 3 includes a partition 31 that divides the closed cross section in the vehicle body fore-and-aft direction, and a flange F6 that extends forward and backward in a vehicle body from an edge 33 of the partition 31 and is formed over the whole circumference of the edge 33 of the partition 31. The flange F6 is connected to the floor cross member 2 with the side sill 1 between them.SELECTED DRAWING: Figure 3
