Lieutenant-General John Manners, Marquess of Granby PC (2 January 1721 – 18 October 1770) was a British Army officer, politician and nobleman. The eldest son of John Manners, 3rd Duke of Rutland, as he did not outlive his father and inherit the dukedom, Manners was known by his father's subsidiary title, Marquess of Granby. He served in the military during the Jacobite rising of 1745 and the Seven Years' War, being subsequently rewarded with the post of Commander-in-Chief of the Forces. Manners was popular with the troops who served under him and many British pubs are still named after him today.
