Headington is an eastern suburb of Oxford, in the county of Oxfordshire, England. It is at the top of Headington Hill overlooking the city in the Thames valley below, and bordering Marston to the north-west, Cowley to the south, and Barton and Risinghurst to the east. The life of the large residential area is centred upon London Road, the main road between London and Oxford.

Marston is a village in the civil parish of Old Marston about 2 miles (3 km) northeast of the centre of Oxford, England. It was absorbed within the city boundaries in 1991. It is commonly called Old Marston to distinguish it from the suburb of New Marston that developed between St. Clement's and the village in the 19th and 20th centuries. The A40 Northern Bypass, part of the Oxford Ring Road forms a long north-west boundary of the village and parish and a limb, namely a distributary, of the Cherwell forms the western boundary.
