Admiral of the Fleet Sir Roger Roland Charles Backhouse GCB GCVO CMG (24 November 1878 – 15 July 1939) was a Royal Navy officer. He served in World War I as a cruiser commander and after the War became a battle squadron commander and later Commander-in-Chief, Home Fleet. Becoming First Sea Lord in November 1938, his major contribution in that role was to abandon the official British policy of sending a major fleet to Singapore to deter Japanese aggression (the Singapore strategy), realising the immediate threat was closer to home (from Germany and Italy) and that such a policy was no longer viable. He died from a brain tumor in July 1939 just before the start of World War II.
