Appleford-on-Thames is a village and civil parish on the south bank of the River Thames about 2 miles (3 km) north of Didcot, Oxfordshire. It was part of Berkshire until the 1974 local government boundary changes. The 2011 Census recorded the parish’s population as 350.
Evidence of Romano-British settlement has been found in a field south of the parish church plus ceramics and human burials of the same period at Manor Farm. In 1968 the Appleford Hoard of 4th-century Roman artefacts was found. It includes Roman coins, pewter ware, and ironomongery including tools, a chain and a padlock. The hoard is now in the Ashmolean Museum, Oxford.
