The invention relates to an external anti-vibration connecting structure for a shipping superstructure. The external anti-vibration connecting structure comprises a shipping body, the superstructure, a bridge deck, a compass deck, and an anti-vibration structure, wherein the superstructure is arranged at the upper end of the shipping body, the bridge deck is arranged at the upper end of the shipping body, the compass deck is arranged at the upper end of the bridge deck, and the anti-vibration structure is arranged at the front end of the superstructure; and the anti-vibration structure comprises wrist plates arranged at the front end of the superstructure and connected with the superstructure in a welding mode, longitudinal girders arranged at the front ends of wrist plates, and fixed plates arranged at the front ends of longitudinal girders. The number of the wrist plates is two, and each wrist plate is in a half moon shape. The number of the longitudinal girders is consistent with that of the wrist plates, one end of each wrist plate is connected with the front end of the bottom of the wrist plate in a welding mode correspondingly, and cross beams are arranged between the two wrist plates. The number of the cross beams is two, and the two wrist plates and the two cross beams define a closed-loop structure.
