The 28th Massachusetts Infantry regiment was the second primarily Irish American volunteer infantry regiment recruited in Massachusetts for service in the American Civil War. The regiment's motto (or cry) was Faugh a Ballagh (Clear the Way!)

The 28th was raised in Boston and received its initial training at Camp Cameron in Cambridge and Somerville. The unit underwent additional training at Fort Columbus in New York Harbor before being dispatched in early 1862 for its first active duty assignment.

After serving briefly under Gen. Benjamin Butler in the Carolinas and with the 9th Corps during the Confederate Army of Northern Virginia's first campaign into the North, the 28th Massachusetts was assigned to the II Corps as the fourth regiment of the famed Irish Brigade, commanded by Brig. Gen. Thomas Francis Meagher.

Known for their distinctive Tiffany-embroidered green flag and Gaelic war cry, "Faugh a Ballagh" (Clear the Way), the Irishmen of the 28th Massachusetts saw action in most of the Union Army's major eastern theatre engagements – Antietam, Fredericksburg, Chancellorsville, Gettysburg, the Overland Campaign, and the siege of Petersburg – and were present for Gen. Robert E. Lee's surrender to Gen. Ulysses S. Grant at Appomattox Court House.
