Center Township is a township in Beaver County, Pennsylvania, United States. As of the 2020 census, it had a population of 11,649. It is a suburban community located approximately 25 miles (40 km) northwest of Pittsburgh. It is home to two colleges, Penn State Beaver and Community College of Beaver County. Center Township is also a retail center for Beaver County, home to the Beaver Valley Mall.

Prior to colonial explorers, native Indians traveled the "Glade Path", an important trail crossing the future township from north to south. One family of settlers in Beaver Valley, the Bakers, made their home in 1774 in the hills above Raccoon Creek near what is now Pleasant Drive in Center Township. At that time, all lands south of the Ohio had been claimed by Virginia, with the seat of government at Pittsburgh. During the course of the Revolutionary War, Fort McIntosh was constructed at Beaver to aid settlers in defense against the Indians and the British at Detroit. Supplies were brought from Pittsburgh along the old Indian path. The trace was renamed Brodhead's Road, after the commander of Fort McIntosh.

When Beaver County was formed in 1800, three townships were created on the south side of the Ohio River: Hanover, First Moon and Second Moon. Later (in 1812) the area was reorganized into four townships. One of these was Moon, the parent of Center. Over the years, other communities were formed from Moon: Raccoon Township in 1837, Phillipsburg Borough in 1840 (now Monaca), and Potter Township in 1912.

In 1914, a serious dispute among Moon Township residents split the township, separating the heavily populated suburban section in the north from the much larger sparsely populated region in the south and west. On November 24, 1914, after a second election, the court decreed that the larger southern section be known as Center Township. Eighteen years later, the remaining portion of Moon in the north was annexed by Monaca, becoming that borough's Fourth and Fifth Wards (Monaca Heights and Colona Heights). In early November 2003, the largest hepatitis A outbreak in American history occurred due to contaminated green onions at the defunct Chi-Chi's Mexican restaurant in the Beaver Valley Mall in Center Township. There were at least 660 confirmed cases, and four deaths.

According to the United States Census Bureau, the township has a total area of 15.4 square miles (39.8 km), of which 15.1 square miles (39.0 km) is land and 0.31 square miles (0.8 km), or 1.95%, is water.

Center Township is bordered to the northeast by the borough of Monaca, to the south by Hopewell Township and the city of Aliquippa, to the northwest by Potter Township, and to the west by Raccoon Township. To the north, across the Ohio River, is the borough of Beaver, and Conway is to the east across the river. Since Center Township does not have a mailing center, all its residents have either a Monaca or Aliquippa mailing address.
