Admiral Sir Bertram Home Ramsay, KCB, KBE, MVO (20 January 1883 – 2 January 1945) was a Royal Navy officer. He commanded the destroyer HMS Broke during the First World War. In the Second World War, he was responsible for the Dunkirk evacuation in 1940 and planning and commanding the naval forces in the invasion of France in 1944.
Ramsay joined the Royal Navy in 1898. As a naval cadet, he was posted to HMS Crescent in April 1899. Later serving on HMS Britannia, he became a midshipman within a year. By the middle of 1902 he was an acting sub-lieutenant, and he was confirmed in this rank on 15 September 1902. He was promoted to lieutenant on 15 December 1904.
The Census 1911 reveals him serving as Flag Lieutenant to Rear Admiral Douglas Gamble on HMS Bacchante (1901) in the Mediterranean. The ship was captained at the time by Reginald Tyrwhitt.
