Rear-Admiral Sir Morgan Charles Morgan-Giles, DSO, OBE, GM, DL (19 June 1914 – 4 May 2013) was a Royal Navy officer, decorated during the Second World War, who later served as a Conservative Member of Parliament. At the time of his death, he was the oldest living former member of the House of Commons.

The eldest son of Francis Charles Morgan-Giles OBE, Naval architect and yacht designer, and Ivy Constance Morgan-Giles (née Carus-Wilson), Morgan-Giles' childhood was spent idyllically "messing around with boats" at Teignmouth, where his father had his boatyard. The family lived across the river at Shaldon, necessitating a short row across the Teign River several times a day. Morgan-Giles said that he could "row before he could walk".

Morgan-Giles' first memory was of his father (on sick leave from the Royal Navy with petrol poisoning during the First World War) building a little dinghy for his young son. Due to the war, there was a shortage of good wood, and legend has it that FC Morgan Giles could not find quite what he wanted to finish her off. His wife came home one day to find the best table in the house had mysteriously vanished but the little boat had a new mahogany transom. When the boat was completed (she was called Pip Emma and is now in the National Maritime Museum Cornwall in Falmouth) the three-year-old Morgan was placed in her and launched out to sea. This started off his lifelong passion for boats and the sea.

As a child Morgan-Giles' family would spend their Easter holidays at Swallerton Gate on Dartmoor. In 1928, when he was 14 he managed to save enough pocket money to buy a Douglas flat-twin motorbike for £2, which was also 14 years old. In addition to this form of transport, he was lent a little motor boat, one of the first in-board motor boats, originally designed and built by his father, called Shush (also in the National Maritime Museum Cornwall) in which he spent nearly every waking hour, buzzing about on the river. His father built a succession of sailing boats for Morgan, and his brothers and sister, to race, which they did with great success at regattas up and down the coast of Devon and Cornwall.

Morgan-Giles was educated at Clifton College. At Clifton he demonstrated his ability to work the system as he wanted to crew for his father in a sailing race, but was told that instead he must attend a cricket match between Clifton College and Tonbridge School. So he took the train to London, passed through the turnstile at Lord's Cricket Ground; straight in, round and out again, and took the train down to Ryde, on the Isle of Wight, where father and son entered the race, and won; this was the Prince of Wales Cup, one of the most prestigious National dinghy races of the year.

Morgan-Giles joined the China Fleet as a midshipman at 18 in 1932, serving on a variety of ships, including Yangtze river patrol boats. He first sailed in the training cruiser HMS Frobisher to the West Indies and the Baltic. He was then appointed to the Australian destroyer HMAS Voyager before serving in HMS Cumberland, Suffolk and Cornwall on the China Station before returning home to join the torpedo school at HMS Vernon. He was promoted to Torpedo Specialist in 1938.

During the Second World War, Morgan-Giles served on HMS Arethusa during the Norwegian Campaign in 1940, HMS Emerald escorting Atlantic convoys, and took part in the Battle of Oran. In 1941, he was sent to the Suez Canal, where he was in charge of the anti-magnetic mine campaign. In April of that year, he acted as a liaison with the Royal Air Force using Wellington bombers as torpedo bombers. During his time with No. 201 Group RAF at Dekheila he survived three serious aeroplane crashes (one of which he was the sole survivor). Following a period of staff training at the Royal Naval College, Greenwich, Morgan-Giles was then sent to the Far East as Staff Officer Operations of Force W. There he accepted the Japanese surrender of Thailand.

Morgan-Giles was awarded the George Medal for "gallantry and undaunted devotion to duty" during bomb and mine disposal work while serving at HMS Nile, the naval base at Ras el-Tin Point, Alexandria. Morgan-Giles had been sent to help clear the ships from the harbour as quickly as possible, because they were loaded with explosive and ammunition, and (although unknown at the time) mustard gas. Whilst on board HMS Zetland, helping to get move the ship out of the harbour to minimise losses, a bomb struck a nearby ammunition ship, and he was hurled the length of the deck, but was uninjured amongst the wreckage and fire. He was nevertheless able to climb onto an American Liberty ship, SS Lyman Abbott that was blocking the harbour exit. Once aboard, he found not a single man alive, and no power, therefore no method of weighing her anchor. He, and two other men that had joined him, were therefore forced to tamp explosive into the anchor chain, light the fuse and take cover. The explosion severed the cable, and they eventually managed to get the ship towed out of the way. It emerged after the war that Lyman Abbott had also had mustard gas on board. Had Lyman Abbott been hit whilst still inside Bari's harbour, the casualties from the mustard gas would likely have been extensive.
