The invention relates to a lightweight rear axle fixed bracket of an off-road vehicle, and the lightweight rear axle fixed bracket comprises a bolt seat main body and is composed of a girder connecting section and an adjusting block connecting section; the girder connecting section comprises a girder installing plate and stiffener plates, the two ends, in the long-axis direction, of each stiffener plate are respectively provided with a bolt connecting hole, and the girder installing plate is provided with an installation positioning hole; the central position of the adjusting block connecting section is provided with a circular through hole through which an adjusting block passes, the middle positions of the upper and lower ends of the adjusting block connecting section are respectively provided with a groove gradually sunken to the circular through hole. The fixed bracket disclosed by the invention has the advantages that on the basis of ensuring the structural strength of the fixed bracket, by changing the structure form of the fixed bracket and arranging a U-shaped opening and a waist-shaped through hole on an after-frame connecting section, the overall weight of the fixed bracket is reduced from original 48 kg to 40.1 kg, so that the weight-loss ratio reaches 16.4%, thereby achieving the purpose of reducing the weight of the fixed bracket.
