New Beaver is a borough in southern Lawrence County, Pennsylvania, United States.

The cement plant was located outside the borough of Wampum in what remained as Big Beaver Township.

The area of Big Beaver Township suffered growth and loss over the next seventy five years.

The Borough of Wampum, in search of a larger tax base, decided to annex the Medusa Cement Plant from Big Beaver Township.

Shortly after this, the Borough of Ellwood began to consider annexing the property south of the cement plant.

The charter was signed on November 18, 1959, however the community continued to operate as a township until elections could be held in 1961.

A portion of Pennsylvania State Game Lands Number 148 is located in New Beaver.
