The 1st Wisconsin Infantry Regiment was a volunteer infantry regiment in the Union Army during the American Civil War. The regiment was originally raised as for a three-month term under President Lincoln's April 1861 call for 75,000 volunteers, and served briefly in the eastern theater during that enlistment. After the three-month term expired, however, the regiment was re-established for a three-year term and spent most of the remainder of its service in the western theater of the war, serving in many of the major battles in Tennessee, Kentucky, and Georgia.
