Ratley is a village in the civil parish of Ratley and Upton, Stratford-on-Avon District, Warwickshire, England. The population of the civil parish in 2011 was 327. It is on the north-west side of the Edge Hill escarpment about 200 metres (660 ft) above sea level.
The remains of a 12th-century motte and bailey castle are just outside the village.
The Church of England parish church is Decorated Gothic and almost all of it was built in the 14th century. It is one of a few churches in England dedicated to St. Peter ad Vincula. In the church is a book where people with the surname of Ratley can sign their names.
The Battle of Edge Hill, the first battle of the English Civil War, was fought very near the village. The former Church of England school and local Post Office buildings are still standing but have been converted into houses.
Upton House is less than 1 mile (1.6 km) from the village. It houses a fine art collection and is managed by the National Trust.
In 1922 the Edge Hill Light Railway was built through the village to carry ironstone from a local quarry. It became disused after a few years and was dismantled in 1946.
