A wildcatter is an American term for an individual who drills wildcat wells, which are exploration oil wells drilled in areas not known to be oil fields. Notable wildcatters include Glenn McCarthy, Thomas Baker Slick, Sr. and Mike Benedum, Joe Trees, Clem S. Clarke, and Columbus Marion Joiner, the latter the finder of the East Texas Oil Field in 1930.

According to tradition, the origin of the term in the petroleum industry comes from Wildcat Hollow, now in Oil Creek State Park near Titusville, Pennsylvania. Wildcat Hollow was one of the many productive fields in the early oil era. A speculator who risked his luck by drilling in this narrow valley shot a wildcat, had it stuffed and set it atop his derrick. The mounted cat gave its name to the hollow. Because the area was largely untested and somewhat away from Oil Creek Flats, the term Wildcatter was coined, describing a person who risked drilling in an unproven area.
