Admiral Robert Dudley Oliver (31 October 1766 – 1 September 1850) was a senior officer of the British Royal Navy during the early nineteenth century, who served in the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars with distinction, seeing action several times during his career, particularly with the fleet in the Caribbean during 1782. After briefly serving in the War of 1812 off the coast of Virginia, Oliver retired from the Navy, settling near Dublin, where he was an active member of religious societies until his death in 1850.
