History
A significant Native American village, now known as The Fisher Site, was once located in what is now Richhill Township.
One researcher claims that the first white (non-Native Americans) settlers in what later became Greene County were a Dr. Thomas Eckerlin and his two brothers, who lived at the mouth of Dunkard Creek beginning in 1745. Other early pioneers in the mid-1750s include the Provins and Cox families; they lived along Whiteley Creek and at Ten Mile on Castile Run respectively. John Armstrong settled on Muddy Creek and claimed to have the first white child born west of the Monongahela River.[4]
Writing in 1875–1876, another researcher stated that early settlers were largely of Scots, Irish and German origin; that the county was the site of much conflict between early settlers and Native Americans; and that the Great Catawba Indian War Path crossed the Dunkard valley and ran south to Monongalia County, West Virginia.[5][6]
What is now Greene County was originally claimed by Virginia. Later it was part of Washington County, Pennsylvania. The Pennsylvania State Legislature created Greene County on February 9, 1796.[7] The capital, Waynesburg, was named after Anthony Wayne, a general in the American Revolutionary War and Native American conflicts.[8]
Garards Fort, an unincorporated community southeast of Waynesburg, is known for the Revolutionary era Corbly family massacre.

Government and politics
Greene County was long a Democratic stronghold, due to the strong unionization of the county's steel mills; between 1932 and 2000, the Democratic presidential candidate won the county in every election except in the Republican landslide of 1972. Due to the decline of the Pittsburgh area's steel industry (similar to other Appalachian counties), and the Democratic Party's shift on cultural issues like environmental safety and firearms, the county was a landslide for the Republican Party in 2024 for Donald Trump who won the county with 71.5% of the vote.

Economy
Coal and natural gas have a long history in Greene County. A 19th century history lists numerous prominent citizens involved in the coal industry.[38] Some 200 deaths were caused by the Mather Mine disaster of 1928. The Shannopin coal mine extracted coal from the Pittsburgh Seam from 1926 until it closed in 1993. Hatfield's Ferry, a coal-burning power plant near Monongahela Township, was a significant source of employment for local residents for over 40 years. It was shut down in 2013[39] and dismantled in 2023.[40]
Natural gas extraction, including fracking the Marcellus Shale formation, is prevalent in the county.[41] While it has brought new jobs to the area, opponents claim the process contaminates drinking water.[42][43][44] A U.S. Geological Survey report notes that it creates "potentially serious landscape disturbances."[45]
Greene County is home to Hill Top Energy Center, a modern 665-megawatt natural gas-fired power plant built on the site of a former coal mine.[46] Blackstone Energy Transition Partners acquired the plant in 2025.[47][48] In August 2025 International Electric Power announced plans to build a 944-megawatt natural gas-fired power plant in Greene County to power a proposed data center. State and federal approvals for the new power plant will be required.[49]
State Correctional Institution – Greene (SCI Greene), located in Waynesburg, provides jobs for about 670 people.[50]
Greene County's development commission has assisted area businesses since 1998.[51] Meadow Ridge Business Park has served the county since the early 2000s.[52][53]
