Blockley is a village, civil parish and ecclesiastical parish in the Cotswold district of Gloucestershire, England, about 3 miles (5 km) northwest of Moreton-in-Marsh. Until 1931 Blockley was an exclave of Worcestershire.

The civil and ecclesiastical parish boundaries are roughly coterminous, and include the hamlets of Draycott, Paxford and Aston Magna, the residential development at Northwick and the deserted hamlets of Upton and Upper Ditchford.

Blockley village is on Blockley Brook, a tributary of Knee Brook. Knee Brook forms the northeastern boundary of the parish and is a tributary of the River Stour.

In AD 855 King Burgred of Mercia granted a monastery at Blockley to Ealhhun, Bishop of Worcester for the price of 300 solidi. In 1086 the Domesday Book recorded that the Bishop of Worcester held an estate of 38 hides at Blockley. The Bishops of Worcester retained the estate until 1648, during the English Civil War, when the Parliamentary Trustees sold it. After the restoration of the English monarchy the estate was restored to the Bishop of Worcester, whose successors held the manor until at least 1781.

The Church of England parish church of St. Peter and St. Paul is late Norman, built in about 1180. The ecclesiastical parish now forms part of the Vale and Cotswold Edge team of Church of England churches, with the Team Vicar remaining responsible for Blockley and its outlying villages of Paxford, Draycott and Aston Magna, as well as the parish of Bourton-on-the-Hill.

The church is used as St Mary's Roman Catholic church in the Father Brown television series and the vicarage as the presbytery, Father Brown's residence.

The Baptist Chapel was built in 1835.

In 1715 the Vicar, the Rev. Dr. Erasmus Saunders, had a new school built for the parish. Blockley still has a Church of England primary school.
