Admiral of the Fleet George Byng, 1st Viscount Torrington,, of Southill Park in Bedfordshire, was a Royal Navy officer and statesman. While still a lieutenant, he delivered a letter from various captains to Prince William of Orange, who had just landed at Torbay, assuring the Prince of the captains' support; the Prince gave Byng a response which ultimately led to the Royal Navy switching allegiance to the Prince and the Glorious Revolution of November 1688.

Admiral of the Fleet is a five-star naval officer rank and the highest rank of the Royal Navy, formally established in 1688. The five-star NATO rank code is OF-10, equivalent to a field marshal in the British Army or a Marshal of the Royal Air Force.
