An ignition apparatus for an internal combustion engine includes at least one pre-chamber and at least one ignition source. The pre-chamber is coupled to the ignition source in the longitudinal extension direction of the ignition apparatus such that it can rotate about a center axis of the ignition apparatus without offset between at least two rotation direction positions of the pre-chamber relative to the ignition source. In at least one decoupling rotation direction position, the pre-chamber is reversibly detachable from the ignition source and can be spaced from the ignition source in the longitudinal extension direction.
