The Free Frank McWorter Grave Site, near the Pike County, Illinois city of Barry, is the grave site of former slave Frank McWorter. McWorter, originally from South Carolina, bought his and 14 other slave relatives' freedom during the mid-19th century in Kentucky.
In 1836 he was the first African American before the American Civil War to plat and register a town, New Philadelphia, Illinois. The New Philadelphia Town Site, abandoned by the early 20th century, was designated a National Historic Landmark in 2009 for its history and archaeological resources.
McWorter's grave site was listed on the National Register of Historic Places in 1988. It is located about 4 miles east of Barry, Illinois off U.S. Route 36.
