George Keith, 10th Earl Marischal (Inverugie Castle, 2nd April 1692/3 – Potsdam, 28th May 1778) was a Scottish Army Officer who lead Jacobite forces during the Jacobite Rising of 1719, who would later serve in the Prussian Army, serving as an Ambassador to the Kingdom of France, Kingdom of Spain, and later the Kingdom of Great Britain under Fredrick II of Prussia.
He is the last Earl Marischal of Scotland, with the title being attainted for a time due to Keith's involvement with the Jacobites, with the honours being restored in 1759 due to him warning Britain of Spain's plan to join on the side of France during the 7 Years War.
He has a younger brother; James Francis Edward Keith, who served with his brother in Scotland, and later would become General-Feldmarshal of Prussia to command and be killed in action during the 3rd Silesian War (Austro-Prussian front of the 7 Years War)
