The Port Kennedy Bone Cave is a limestone cave in Port Kennedy, Pennsylvania, USA. The Bone Cave "contained one of the most important middle Pleistocene (Irvingtonian, approximately 750,000 years ago) fossil deposits in North America".[1]

The fossils in the cave were investigated by noted 19th century palaeontologists Edward Drinker Cope, Henry C. Mercer, and Charles M. Wheatley. Some of the fossils, such as an unnamed member of Genus Dicaelus are unique to this cave and have not been identified elsewhere.[2]

The cave was originally discovered by limestone miners in the 19th century. The cave was later filled in with asbestos-bearing industrial refuse and the cave's location was lost. The land is now part of the Valley Forge National Historical Park. In 2005, the National Park Service and geologists rediscovered the cave.[3]

It has been rumored that the quarry near where the cave is located near holds a crashed locomotive, which was used in the shooting of a now lost silent film in 1915, The Valley of Lost Hope.[3]
