A fuel injection valve for an internal combustion engine is disclosed which comprises a housing (2), an electromagnetic actuator with an armature (20) and a valve needle (4). The armature (20) is axially movable relative to the housing (2) and to the valve needle (4) and has a recess (36). The valve needle (4) comprises a stopper element (38) being positioned in the recess (36) of the armature (20). The stopper element (38) and the recess (36) are configured such that the stopper element (38) is operable to engage into a form-fit connection with the armature (20) for initiating a movement of the valve needle (4) and to engage in a further form-fit connection with the armature (20) for limiting a movement of the valve needle (4) relative to the armature (20).
