Oil Creek State Park is Pennsylvania state park on 6,250 acres (2,529 ha) in Cherrytree, Cornplanter and Oil Creek Township Townships, Venango County, Pennsylvania in the United States. The park is adjacent to Drake Well Museum, the site of the first successful oil well in the United States, that was drilled under the direction of Colonel Edwin Drake.

While the creek is the park's main recreational attraction, it also contains the sites of the first oil boomtown and much of Pennsylvania's original oil industry.
The park contains a museum, tableaux, and trails to help visitors understand the history of the oil industry there, and an excursion train.Oil Creek State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "Twenty Must-See Pennsylvania State Parks".
