George Shelvocke (baptised 1 April 1675 – 30 November 1742) was an English Royal Navy officer and later privateer who in 1726 wrote A Voyage Round the World by Way of the Great South Sea based on his exploits.
It includes an account of how his second captain, Simon Hatley, shot an albatross off Cape Horn, an incident which provided the dramatic motive in Samuel Taylor Coleridge's poem The Rime of the Ancient Mariner.
