Sharon is a city in Mercer County, Pennsylvania, in the United States, 75 miles (121 km) northwest of Pittsburgh. It is part of the Youngstown–Warren–Boardman, OH-PA Metropolitan Statistical Area.
Sharon was settled in 1795, incorporated as a borough on October 6, 1841, and incorporated as a city on December 17, 1918. The city operated under the PA third-class city charter until 2008, at which point it adopted a home rule charter under which the elected position of mayor was replaced with a hired city manager and financial officer. On April 20, 1936, a large fire swept through Sharon's commercial district, causing damage estimated at $1 million (1936 dollars).
The founding families of Sharon first settled on a flat plain bordering the Shenango River (this area is situated between two hills and is the current location of Sharon's downtown business district). According to local legend, the community received its name from a Bible-reading settler who likened the location to the Plain of Sharon in Israel.
