[2] "St Clement's" is usually taken to describe a small triangular area from The Plain (a roundabout) bounded by the River Cherwell to the North, Cowley Road to the South, and the foot of Headington Hill to the East.

It also refers to the ecclesiastical parish of St Clement's which includes some neighbouring areas and is used in the names of local City and County electoral districts.

The area's main road, St Clement's Street (often shortened to just "St Clement's"), links The Plain near Magdalen Bridge with London Place at the foot of Headington Hill at the junction with Marston Road to the north.

At the point where St Clement's reaches South Park, there is a junction with Morrell Avenue to the southwest.

[4] The Old Black Horse (102 St Clement's Street) is a 17th century coaching inn and one of the few buildings in the area to survive the English Civil War.
