Admiral Sir William Hutcheon Hall, (c. 1797 – 25 June 1878), was a British Royal Navy officer. He served in the First Anglo-Chinese War and Crimean War. He was one of the first British officers to make a thorough study of steam engines. In China, he commanded the iron steamship "Nemesis" of the East India Company. Although it was not officially commissioned as a Royal Navy warship, the Admiralty enabled Hall to count his time in the "Nemesis" as if he had served in one of Her Majesty's Ships.
