Warwickshire is in the West Midlands region of England. The county town is Warwick, although the largest town is Nuneaton in the far north of the county.  Warwickshire is bounded to the north-west by the West Midlands metropolitan county and Staffordshire, by Leicestershire to the north-east, Northamptonshire to the east, Worcestershire to the west, Oxfordshire to the south and Gloucestershire to the south-west.

Warwickshire is divided into five districts: North Warwickshire, Nuneaton and Bedworth, Rugby, Stratford, and Warwick. There are no cities in Warwickshire since both Coventry and Birmingham were incorporated into the West Midlands county in 1974 and are now metropolitan authorities in themselves.

The market towns of northern and eastern Warwickshire were industrialised in the 19th century, and include Atherstone, Bedworth, Nuneaton, and Rugby. Major industries included coal mining, textiles, engineering, and cement production, but heavy industry is in decline. In central and western Warwickshire prosperous towns include Leamington Spa, Stratford-upon-Avon, Kenilworth, Alcester, and Warwick. The south of the county is rural and sparsely populated, and includes a small area of the Cotswolds. The only town in the south of Warwickshire is Shipston-on-Stour.

Warwickshire is perhaps best known for being the birthplace of William Shakespeare from Stratford-upon-Avon. Even today, road signs at the county boundary describe Warwickshire as "Shakespeare's County".

Several major motorways run through Warwickshire including; the M40 connecting London to Birmingham, and serving Leamington Spa, Warwick, and Stratford. The M6, which connects the north-west of England and the midlands to the M1 (and then on to London), and the M69 Coventry to Leicester motorway which serves Nuneaton.

Two major railway lines pass through Warwickshire. The Chiltern Main Line from London to Birmingham and the West Coast Main Line (WCML) through Warwickshire. At Rugby the WCML splits into two lines running west through to Coventry and Birmingham, and the "Trent Valley Line" running north-west towards Stafford and north-west England. Coventry Airport is located in the Warwickshire village of Baginton.
