'Aimwell' was a British unrealised plan for the amphibious recapture of the German-occupied island of Alderney in the Channel Islands group (summer 1942).

The plan was never fully formulated and its development was dropped after the realisation that any continued British military retention of the islands, lying as it does just off the coast of German-occupied France, would be virtually impossible in the face of German air superiority from the other Channel islands and the French mainland.
