'Ratweeek' (iii) was an Allied proposed series of assassinations, as a logical extension of 'Ratweek' (ii), directed at German military leaders and intended for realisation in support of the 'Neptune' (iii) and 'Overlord' invasion of Normandy (summer 1944).

The operation was not undertaken for a number of reasons, most especially the fear of German reprisals against Allied prisoners of war.
