Operation Shark was a counter-terrorism operation conducted by the military and police forces of British Mandatory Palestine in response to the King David Hotel bombing. Conducted through a series of house to house searches, the operation was intended to deprive the Irgun organization of manpower, hideouts, and weaponry.

The British administrative headquarters for Mandatory Palestine, housed in the southern wing of the King David Hotel in Jerusalem, were bombed in a terrorist attack on July 22, 1946, by the militant right-wing Zionist underground organization Irgun during the Jewish insurgency. 91 people of various nationalities were killed, including Arabs, Britons and Jews, and 46 were injured.
