32nd Regiment Indiana Volunteer Infantry was a Union Army infantry regiment during the American Civil War. It was also known as Indiana's "1st German" regiment because its members were mainly of German descent. Organized at Indianapolis, the regiment's first recruits mustered into service on August 24, 1861. From 1861 to 1865, the 32nd Indiana was attached to the first Army of the Ohio and the Army of the Cumberland, where it served in the Western Theater.
