Frilford is a hamlet and civil parish in the Vale of White Horse district of Oxfordshire, England. It is about 3 miles (4.8 km) west of Abingdon at the junction of the A415 and A338 roads. It was part of Berkshire until it transferred to Oxfordshire in the 1974 boundary changes.

The parish of Frilford has two significant archaeological sites: a Roman villa, and a cemetery on Frilford Heath that appears to include both Roman and Saxon burials. A further complex of remains, including a Roman shrine and amphitheatre, is often referred to as being in Frilford but lies to the south of the village, just inside the boundary of Marcham parish.

Frilford is part of the Church of England parish of Marcham. It has no Church of England parish church of its own, but a Congregational chapel was built at Frilford in 1841.

Frilford Heath Golf Club is to the east of the village. Abingdon Preparatory School at Frilford, formerly Joscas, is a preparatory school.

Three Stagecoach in Oxfordshire bus routes serve Frilford. Route 15 to Witney and Abingdon. Routes S8 (via Abingdon) and S9 (via Cumnor) to Wantage and Oxford.

Notable people from Frilford include Dr Gary Botting, born at Oakley House Maternity Hospital on 19 July 1943, who became a noted Canadian extradition lawyer.
