Lyneham Long Barrow is a Neolithic chambered long barrow near Lyneham, Oxfordshire, likely one of the earliest surviving structures in the area at 5,000 to 6,000 years old. The mound extends up to 52 m long and 19 m wide with a 1.8 m tall standing stone nearby. A partial excavation in 1894 by Lord Moreton and Edward Conder uncovered two internal chambers containing human and animal bones, pottery, and charcoal, along with secondary Anglo-Saxon burials cut into the top of the mound.
