Korean War Arthur Gilbert Trudeau (5 July 1902 – 5 June 1991) was a lieutenant general in the United States Army.

Trudeau was born in Middlebury, Vermont, on 5 July 1902, and entered the United States Military Academy at West Point in 1920.

In January 1946, Trudeau was appointed as a judge at the military tribunal of Gen. Masaharu Homma in view of the war crimes committed by his command during the invasion of the Philippines, sitting on the bench along with Major General Leo Donovan, Major General Basilio Valdes, Brig.

He received the Silver Star by personally leading a reconnaissance team to scout a strategic position, Pork Chop Hill, while it was under heavy enemy fire.

Although the contents of the memorandum were not made public, Trudeau was noted for his vigorous anti-Communist statements, and he often clashed with other government officials over their differing views of communist intentions.
