The site of the final encounter between the Union and Confederate armies before they fought against each other in the Battle of Gettysburg during the American Civil War, Hanover has since become known as the "Snack Food Capital of the World" due to the establishment of multiple food manufacturing businesses there during the 20th century. Notable companies based in the borough include Utz Brands and Snyder's of Hanover.

In 1727, John Digges, an Irish nobleman of Prince George's County, Maryland, obtained a grant of of land where Hanover is now located from Charles Calvert, 5th Baron Baltimore. The area was called Digges Choice, and in 1730, a group of Catholics started the settlement that became known as the Conewego Settlement. Settlers from both Maryland and Pennsylvania began moving into the area in the 1730s. At this time, Maryland and Pennsylvania did not agree on the northern border of Maryland and the southern border of Pennsylvania, and the area that is now Hanover was in the disputed area claimed by both states. This led to numerous disputes about property ownership from the 1730s until 1760. The dispute was settled when Maryland and Pennsylvania hired British expert surveyors Charles Mason and Jeremiah Dixon to survey what became known as the Mason–Dixon Line. This line was surveyed between 1763 and 1767, and put an end to decades of disputes over rights and ownership. In 1745, a Scot Irishman named Richard McAllister (father of Matthew McAllister) purchased the tract of land upon which the original town of Hanover was built. McAllister was a Presbyterian who had recently migrated from the Cumberland Valley. Hanover at that time was covered with a dense forest of hickory, walnut, and oak trees. McAllister erected a log house at what is now the corner of Baltimore and Middle streets, and opened a store and tavern. In 1763, McAllister divided his farm into lots and founded the town of Hanover. German settlers nicknamed the settlement "Hickory Town" after the thick groves of hickory trees that grew in the area. The name Hanover was suggested by Michael Tanner, who was one of the commissioners who laid out York County in 1749 and owned large tracts of land southeast of the town. Tanner's choice of the name came from the fact that he was a native of Hanover, Germany. The town's founders, who wanted to please the German settlers, agreed to the name. Hanover was also sometimes referred to as "McAllister's Town" in its early years.

Thomas Jefferson spent the night of April 12, 1776 at the Sign of the Horse, an inn, owned by Caspar Reinecker on Frederick Street. Records indicate that Jefferson paid "Rhenegher" 11 shillings, 6 pence for dinner and lodging. He was on his way from Monticello to Philadelphia to attend the first meeting of the Continental Congress, where on June 10 he would begin to draft the Declaration of Independence. At the time, Hanover was located at the crossing of two well traveled roads, one from the port of Baltimore to points north and west and the other between Philadelphia and the Valley of Virginia. When Jefferson returned from Philadelphia to Monticello, he again dined and spent the night of September 5 at Reinecker's inn. At the start of the Revolutionary War, Hanover consisted of about 500 homes, most of which were built out of logs. After the War of 1812, the town experienced only minor growth until 1852, when construction of the Hanover Branch Railroad to Hanover Junction was completed. In 1858 the Gettysburg Railroad opened a railroad link westward to Gettysburg. The Hanover and York Railroad completed a rail line to York in 1876.

During the American Civil War, the Battle of Hanover was fought on June 30, 1863. Union cavalry under Judson Kilpatrick encountered Confederate cavalry under J. E. B. Stuart and a sharp fight ensued in the town and in farm fields to the south, particularly along Frederick Street. The final encounter between Union and Confederate forces prior to the Battle of Gettysburg, this inconclusive engagement delayed the Confederate cavalry on their way to the Battle of Gettysburg. Three days before the battle, another detachment of Virginia cavalry had briefly occupied Hanover, "collecting" supplies and horses from local citizens. Over the years, its industries have included the making of cigars, gloves, silks, flavine, water wheels, flour, shirts, shoes, machine shop products, furniture, wire cloth, and ironstone grinders. The town has lent its name to a brand of canned vegetables, and a mail order gift company based there. Hanover's first newspaper, Die Pennsylvania Wochenschrift, was published in German in 1797. In 1805, the "Hanover Gazette" followed suit, also published in German. The Hanover Historic District, Eichelberger High School, George Nace (Neas) House, and US Post Office Hanover are listed on the National Register of Historic Places.

On July 13, 1991, Hanover's town square was the site of a two day race riot. During the summer, White residents were upset by the presence of young Black men in the town square, who had begun to gather there after the local parks were temporarily closed. In addition, two young, interracial couples had been seen walking downtown. In the lead up to the riot, White residents spat on the Black men visiting their girlfriends in the town square, while the Baltimore Sun reported that there had been tension "building for several weeks," and the Hanover Evening Sun reported that at least one resident "had heard rumors throughout the week that a motorcycle gang was coming into town to start trouble with a few interracial groups of juveniles."
