Cotswolds (sometimes called "The Cotswolds") was a European Parliament constituency covering the counties of Gloucestershire and Oxfordshire in England.

Before uniform adoption of proportional representation in 1999, the United Kingdom used first-past-the-post for the European elections in Great Britain. The European Parliament constituencies used under that system were smaller than the later regional constituencies and only had one Member of the European Parliament each.

When it was created in 1979, it consisted of the Westminster Parliament constituencies of Banbury, Cheltenham, Cirencester and Tewkesbury, Gloucester, Mid Oxfordshire, Oxford and Stroud.^[1] From 1984 it consisted of Banbury, Cheltenham, Cirencester and Tewkesbury, Gloucester, Stratford-on-Avon, Stroud and Witney. From 1994 it consisted of Cheltenham, Cirencester and Tewkesbury, Gloucester, Stroud, West Gloucestershire and Witney.
