The 202nd Regiment Pennsylvania Volunteer Infantry was an infantry regiment of the Union Army in the American Civil War. Raised in the Harrisburg area and the Coal Region in August and September 1864, the regiment was sent to the Manassas Gap Railroad to guard it against the attacks of Confederate partisan rangers led by John Mosby. Following the Union victory at Battle of Cedar Creek, the regiment helped break up the now unneeded railroad and moved to Alexandria to guard the railroad there. After the end of the war, the regiment served in the Coal Region to suppress labor unrest, and was mustered out in mid-1865.
