Since 1736

 Before the coming of the first settlers in 1736, Newberry Township was inhabited by Susquehannock Indians. Settlers used the Middletown Ferry to access the west bank of the River and reached Newberry Township, settling throughout the Fishing Creek Valley. Newberry Township was officially laid out by the authority of the court of Lancaster County in 1742, previous to the erection of York County. It then included nearly all of Fairview Township and the eastern third of Conewago. In 1783, when its boundaries were still unchanged, it contained 33,107 acres of assessed land, had 15 grist and sawmills, and 296 dwelling houses - three more than the town of York then and more than any other township in the county. The population at this period was 1,704, a large proportion of whom were English Quakers. 

Newberry Township is a growing residential community situated between Harrisburg and York. Because of this prime location, there is easy access to enjoy all the cultural events offered by both cities with very little travel while living in a suburban area to the city environment. Newberry Township provides a variety of housing opportunities for all income levels. These opportunities include townhouses, single-family attached and detached homes, mobile homes, and apartments. According to the 2010 Census, the population of the Township was 15,285. The total area of the Township is 30.7 square miles, 30.4 of which is land, and .3 is water.
