The Office of the Inspector General (OTIG) serves to "provide impartial, objective and unbiased advice and oversight to the Army through relevant, timely, and thorough inspection, assistance, investigations, and training." The position has existed since 1777, when Thomas Conway was appointed the first inspector. The department was reorganized many times, and almost abolished on several occasions. In its early days, the department was frequently merged with, or proposed to be part of the Adjutant General. It expanded greatly after the American Civil War, to the point that in 1993 it had around 2,000 officers, non-commissioned officers, and civilian employees.

The current Inspector General is Lieutenant General Gregory J. Brady, who was sworn in on March 17, 2025.
