The 135th Infantry Regiment is an infantry regiment in the Minnesota Army National Guard.

During the Civil War, the First Minnesota Regiment, today the 2nd Battalion, 135th Infantry Regiment (2/135) was the first volunteer regiment to offer its services to President Lincoln. The men of the 1st Minnesota are most remembered for their actions on the late afternoon of 2 July 1863, during the second day's fighting at Gettysburg, resulting in the prevention of a serious breach in the Union defensive line on Cemetery Ridge.

During the battle, the regimental commander, Colonel William J. Colvill gave the order "To the last man", that became the regimental motto.
