Major General Frank Butner Clay (February 26, 1921 – December 30, 2006) was a United States Army officer.

He is buried at Arlington National Cemetery along with his first wife, Patricia Adams Casey Clay (November 1, 1923 – January 1, 1973).

Patricia Clay was the sister of Major Hugh Boyd Casey, who was killed in an airplane crash while serving as an aide-de-camp to the 3d Infantry Division Commander during the Korean War.

They were, in turn, the children of Major General Hugh John Casey of the Army Corps of Engineers, who was the West Point roommate and good friend of General Lucius D. Clay Sr.[1] Clay attended the Valley Forge Military Academy and graduated from Millard Prep School.
