Admiral Sir Frederick Hew George Dalrymple-Hamilton, KCB was a British naval officer who served in World War I and World War II. He was captain of HMS Rodney when it engaged the Bismarck on 27 May 1941.

HMS Rodney was one of two Nelson-class battleships built for the Royal Navy in the mid-1920s. The ship entered service in 1928, and spent her peacetime career with the Atlantic and Home Fleets, sometimes serving as a flagship when her sister ship, Nelson, was being refitted. During the early stages of the Second World War, she searched for German commerce raiders, participated in the Norwegian Campaign, and escorted convoys in the Atlantic Ocean. Rodney played a major role in the sinking of the German battleship Bismarck in mid-1941.
