The 58th Regiment Massachusetts Volunteer Infantry was an infantry regiment that served in the Union Army during the American Civil War. It was one of the four Massachusetts "Veteran Regiments" raised in the winter of 1863–64. Recruits of these regiments were required to have served at least nine months in a prior unit. The regiment was attached to the IX Corps of the Army of the Potomac and took part in Lieutenant General Ulysses S. Grant's Overland Campaign in the spring of 1864. They were in heavy combat during the campaign, suffering casualties during engagements which included the Battle of the Wilderness, Spotsylvania Courthouse, and the Battle of the Crater. They were also involved in several assaults during the Siege of Petersburg.
