Lieutenant General Raymond Stallings McLain (April 4, 1890 – December 14, 1954) was a senior United States Army officer.

During the war, Raymond served as a machine gun company commander with the 36th Division on the Western Front with the American Expeditionary Force (AEF) under General John Pershing until 1919.

After graduating he was posted to the 45th Infantry Division, an Oklahoma Army National Guard formation, as an assistant chief of staff.

He led the artillery overseas during the Allied invasion of Sicily in July – August 1943, where he earned the first of two Distinguished Service Crosses.

He continued to lead the artillery in the Allied invasion of Italy in September, and in the early stages of the Italian campaign, before eventually being sent to England.

His performance in these campaigns gained the respect of many of his Regular Army colleagues, such as Omar Bradley, Mark W. Clark, John P. Lucas, Troy H. Middleton, and even George S. Patton, who was normally very critical of many of his fellow senior officers.

[4] McLain transformed the 90th into a first-class fighting formation, and led it across France in the Allied advance from Paris to the Rhine and in many numerous battles on the Western Front.
