Lawrence County is a county located in the U.S. state of Pennsylvania, United States. As of the 2010 census, the population was 91,108.[1] The county seat is New Castle.[2]

Lawrence County makes up the entire New Castle, PA Micropolitan Statistical Area, which is also included in the larger Pittsburgh-New Castle-Weirton, PA-WV-OH Combined Statistical Area.


Lawrence County was created on March 20, 1849, from parts of Beaver and Mercer counties due to the rapid growth of New Castle, which was primarily in Mercer County but was rapidly expanding into Beaver County. The former borders between Beaver and Mercer Counties are still evident in Lawrence County today, as the northern borders of North Beaver Township, Shenango Township, and Slippery Rock Township with (respectively) the southern borders of Mahoning Township, Hickory Township, and Scott Township make up the former boundaries between Beaver and Mercer Counties. In addition, County Line Road in New Castle where the Lawrence County Courthouse is located also marks the former boundaries.

It was named after naval officer James Lawrence, who died during the War of 1812.[3]


According to the U.S. Census Bureau, the county has a total area of 363 square miles (940 km2), of which 358 square miles (930 km2) is land and 4.5 square miles (12 km2) (1.3%) is water.[4] Major waterways are the Shenango River, Neshannock Creek and the Mahoning River which form the Beaver River. Also, the Slippery Rock Creek and Connoquenessing Creak empty into the Beaver River.
