William Cunnington (1754 – 31 December 1810) was a pioneering English antiquarian and archaeologist of the late eighteenth and early nineteenth century. His work centred on excavating the barrows of Salisbury Plain. The first recorded excavations at Stonehenge were done by William Cunnington & Richard Colt Hoare (archaeologists) in 1798 and again in 1810. They dug around a fallen trilithon and a fallen slaughter stone and they discovered that it had once stood up. Along with Richard Colt Hoare, Cunnington was the subject of an exhibition at the Wiltshire Heritage Museum in 2003. The museum is the keeper of documentation made by Cunnington at the time of his work.
