Copston Magna is a very small village and civil parish in the Rugby borough of Warwickshire, England.

Copston first enters the historical record following the Norman Conquest when, in 1077, a priory was established in Monks Kirby.

It is likely that the present Copston church site housed an oratory in the medieval period.

The most notable building in Copston Magna today is the Anglican St John's Church built in 1849.

Though it is assumed this replaced a medieval chapel, no trace of the older building survives.
