The Cornhill Corn Exchange was a commercial building in the Market Place, Banbury, Oxfordshire, England.

[4] The new building was designed by William Hill of Leeds, built by Messrs Kimberly of Banbury in ashlar stone and was officially opened on 3 September 1857.

The bays of the central section were flanked by pairs of Corinthian order columns supporting a frieze, an entablature and a pediment.

There was a quatrefoil surmounted by a ram's head as well as fruit and foliage in the tympanum, and, at the apex of the pediment, there was a statue of the Roman goddess of agriculture, Ceres.

[4][a] The use of the building as a corn exchange declined significantly in the wake of the Great Depression of British Agriculture in the late 19th century.
