Warrington Township is a township in York County, Pennsylvania United States. It was erected by the authority of the Lancaster County courts in 1744 from neighboring townships. Many of the township’s earliest settlers were of English heritage, immigrating to the township from Lancashire, England. The township’s name derives from an English town of a similar name. In 1783, Warrington Township, which geographically included Washington Township, had 173 houses and 11 mills.
The population was 4,547 at the 2020 census. According to the US Census Bureau, the township has a total area of 36.0 square miles, of which 35.4 square miles is land and 0.6 square miles, or 1.75%, is water. The township completely surrounds the borough of Wellsville. (Also see Comprehensive Plan, pages 37-39)


“The earliest settlements in the region, now embraced Warrington Township, were made in the year 1735, and the township was laid out by the authority of the courts of Lancaster County in 1744. Newberry Township, to which this region at first belonged, had been erected in 1742, and Manchester, the same year. All of these townships, including Hellam, and two or three others, had been erected before York County was separted from Lancaster in 1749. Some of the early Quakers who settled north of the Conowago Creek, came from Warrington, a township along the Mersey River of Lancashire, England. Many actions between the royal and parliamentary forces took place on its soil, during the civil wars of England. The Quakers who came to Bucks County during its first settlement organized a township by the name of Warrington in that country.
Thomas Cookson, deputy surveyor for the county of Lancaster, assisted by William Richardson, made a survey of Warrington Township, which was afterward approved by the Lancaster Courts in 1744. The original shape of this township was that of an irregular pentagon, extending northeast and southwest, and including the present township of Warrington, and a small portion of what is now Adams County, with the Conowago Creek as its southeastern boundary, Newberry to the east and Monaghan to the north.” …History of Warrington Township, As taken from Prowell’s History of York County
