A pet leash is provided. The pet leash includes a housing with a handle formed thereon, a turntable rotationally disposed in the housing, and a hauling rope coiled on the turntable. The housing is provided with a rope hole for leading out the hauling rope, and the handle is provided with a button exposed out of the housing. A user can quickly restrain a pet from running away simply by pressing the button on the leash. The pet would therefore be kept within a controllable range from the user to avoid an accident. Moreover, the user can lock the leash in that state by moving a push button disposed inside the button, and then release the leash from the locked state by moving the push button in the opposite direction.
