General Noël Marie Amédée Garnier-Duplessix or Duplessis (25 December 1860 – 2 March 1928) was a French army officer. Whilst still a colonel he commanded the 2nd Infantry Division in the Allied victory at the First Battle of the Marne before seeing service in the Zaian War in the French protectorate of Morocco. Garnier-Duplessix returned to France in October 1916 and received command of the 37th Infantry Division for the 15 December offensive of the Battle of Verdun and the Nivelle Offensive of April 1917. He received command of the 9th Army Corps in June 1918 and led that unit to victory in the August Battle of Amiens and the autumn Meuse-Argonne Offensive. After the war he was posted to Cilicia in the Franco-Turkish War of 1918–21 where he argued against early withdrawal of troops following the March 1921 Cilicia Peace Treaty.
