Sir Courtenay Boyle, KCH (3 September 1770 – 21 May 1844) was an officer of the Royal Navy during the French Revolutionary Wars. In 1807 he served as a Member of Parliament for Bandon.
Boyle went to sea aboard during the American War of Independence, he went out in HMS Gibraltar, and on returning home was sent to a naval academy at Greenwich. He entered the Royal Navy on 12 September 1780, serving as a midshipman on board the frigate HMS Latona frigate, commanded by Sir Hyde Parker.[4] In this ship he was present at the Battle of Dogger Bank between the squadron under the command of Sir Hyde Parker, the father of the Latona's captain, and a Dutch force under Admiral Johan Zoutman. Some time later he fell from the booms into the orlop, and was obliged to go on shore to recover.
He joined HMS Goliath and remained in that ship until 8 April 1783, when he was sent to the Royal Naval Academy at Portsmouth to finish his nautical studies, where he remained until March 1784. He was appointed to the 28-gun HMS Boreas, under the auspices of Horatio Nelson, and after visiting the West Indies, returned to Spithead in the summer of 1787. With HMS Boreas having been put out of commission, Boyle was received at the recommendation of Nelson on board HMS Barfleur, bearing Lord Hood's flag; and in that ship he continued his services until 25 November 1788, when he was transferred into HMS Leander, the flagship of Admiral Joseph Peyton, by whom, on 5 June 1789, was sent on board the frigate HMS Aquilon, serving with the Mediterranean Fleet. Promoted to lieutenant on 22 November 1790, Boyle subsequently served on board HMS Vanguard. Shortly after this he was confirmed in the rank of lieutenant and appointed to HMS Roebuck.
