The 54th Indiana Infantry, an American Civil War regiment, was organized at Indianapolis, Indiana, on October 28, 1862, with Fielding Mansfield as colonel, and it was made up mostly of volunteers from all over the state. In December, the regiment left for Memphis, Tennessee.

The one-year regiment was organized into 10 companies of infantry and a Field and Staff entity in the fall of 1862. One company mustered into service on October 28, five on October 30, and two each on November 8 and 16, 1862. Like most regiments organized in Indiana at that time, there was a three-month regiment that preceded it; however, while most of the three-month regiments later formed into three-year regiments, the 54th Indiana became a one-year regiment. Several regiments organized immediately before and after the 54th Indiana became three-year organizations.

One year's service was not the only unique attribute of the 54th Indiana. The men in the regiment did not muster out in the same companies that they mustered into (Indiana Adjutant General's Report, Volume 8, vice Volume 7 when mustered in).
