In World War 2, Operation Jael was an Allied deception operation conducted from November 1943 to February 1944 in Europe to convince the Germans that the center of Allied operations would continue to be in the Mediterranean area.

By that time, the large buildup of Allied forces in Britain in preparation for the invasion of northern France (Operation Overlord) was impossible to continue to conceal.

Operation Jael was followed by Operation Bodyguard.
