The Selborne-Fisher scheme, or Selborne scheme, was an effort by John Fisher, 1st Baron Fisher, Second Sea Lord, approved by William Palmer, 2nd Earl of Selborne, First Lord of the Admiralty, in 1903 to combine the military (executive) and engineering branches of the Royal Navy. The main goal was to return control over the movement of a ship to the military officer.

Admiral of the Fleet John Arbuthnot Fisher, 1st Baron Fisher,, commonly known as Jacky or Jackie Fisher, was a British Admiral of the Fleet. With more than sixty years in the Royal Navy, his efforts to reform the service helped to usher in an era of modernisation which saw the supersession of wooden sailing ships armed with muzzle-loading cannon by steel-hulled battlecruisers, submarines and the first aircraft carriers.
