Lyneham is a village and civil parish about 5 miles (8 km) southwest of Chipping Norton, Oxfordshire.

It is bounded to the southwest by the River Evenlode, to the southeast by the A361 road linking Chipping Norton and Burford, and on other sides by field boundaries.

[1] Lyneham Camp or the Roundabout is a former Iron Age hill fort about 1+1⁄2 miles (2.4 km) northeast of the village beside the A361 road.

It was a timber-framed building with a corrugated iron exterior, colloquially called a "tin tabernacle".

[5] In the 19th century the Oxford, Worcester and Wolverhampton Railway was built through the south of the parish along the Evenlode valley.
