The 5th Wisconsin Infantry Regiment was a volunteer infantry regiment that served in the Union Army during the American Civil War. The regiment was engaged in many of the critical battles of the eastern theater of the war, including Antietam and Gettysburg. Immediately after Gettysburg, the regiment was detached from frontline duty and sent north to put down the New York City draft riots. Suffering from attrition in August 1864, the regiment was reorganized as an independent battalion of three companies for the remainder of their service.
