The invention provides a semitrailer and a rear bumper thereof. The rear bumper comprises two stand columns, a cross beam, two connecting pieces and two locking mechanisms. The two stand columns are transversely spaced in parallel and used for being connected with the rear end of the semitrailer. The cross beam and the stand columns are longitudinally arranged at intervals; the cross beam extendsalong the transverse direction; the two connecting pieces are correspondingly arranged between the stand column and the cross beam. Each connecting piece comprises a first connecting arm and a secondconnecting arm; the middle of the first connecting arm in the length direction is hinged to the first end of the second connecting arm, the first end of the first connecting arm is hinged to the standcolumn, the second end of the second connecting arm is hinged to the cross beam, and the second end of the first connecting arm moves in the length direction of the cross beam so that the distance between the cross beam and the stand column can be adjusted. The locking mechanism is arranged corresponding to the connecting piece; each locking mechanism locks the connecting piece and the cross beamso as to keep the distance between the cross beam and the stand column. Therefore, the distance between the rear end face of the rear bumper and the rear end face of the container is adjustable, andthe requirements of relevant laws and regulations can be met.
