This utility model discloses a vehicle door latch, comprising an upper housing and a lower housing arranged opposite to each other. The upper housing has a first hook, and the lower housing has a rotating plate rotatably mounted thereon. A second hook, corresponding to the position of the first hook, is fixed on the rotating plate. A tension spring is connected to the rotating plate, with its other end connected to the lower housing. The upper and lower housings are respectively fixed to the exterior of the vehicle door and body. The first and second hooks interlock to achieve the opening and locking of the vehicle door. Furthermore, the tension of the spring prevents the second hook from easily rotating and disengaging from the first hook, thus preventing the door from closing automatically due to strong winds. This ensures that the latch has strong locking and limiting performance, making the opening and closing of the vehicle door more reliable and safe.
