Disclosed herein is a mounting structure for a vehicle headlamp. In the headlamp mounting structure, damping members, made of rubber, are inserted in middle locations of a headlamp housing to provide the headlamp housing with flexibility. Also, a steel frame is inserted in the damping members to allow for restoration or regulation of the downward deformation of the headlamp housing upon an impact with a headlamp. With the use of the damping members and the steel frame, accordingly, there is no risk of damage to a lens and other elements inside the headlamp housing due to their unintentional movements and collisions. The damping members are also made of a rubber material, ensuring the headlamp is water-tight.
