Oxfordshire, archaically the County of Oxford, abbreviated to Oxon, is a county in the South East of England.

The county has major education and tourist industries and is noted for the concentration of performance motorsport companies and facilities. Oxford University Press is the largest firm among numerous print and publishing firms and the University of Oxford is also linked to the concentration of local biotechnology companies.

The main centre of population is the city of Oxford. Other significant settlements are Banbury, Bicester, Kidlington, and Chipping Norton to the north of Oxford; Carterton and Witney to the west; Thame and Chinnor to the east; and Abingdon, Wantage, Didcot, Wallingford and Henley-on-Thames to the south. Future population growth in the county is hoped to be concentrated around Oxford, Banbury, Bicester, Didcot and Witney.

The highest point of the administrative county is White Horse Hill, in the Vale of White Horse, reaching 856 ft. The highest point in the historic county is near Portobello Farm in the Chiltern Hills at 837 ft.

Oxfordshire’s county flower is the Snake’s-head Fritillary.
