Chadwell St Mary, historically sometimes just called Chadwell, was an ancient parish. The parish included both Chadwell St Mary itself and the area to the south where the port town of Tilbury developed from the 19th century. In 1912, the parish became the Tilbury Urban District. That urban district and the civil parish of Chadwell St Mary were abolished in 1936 on the creation of the larger Thurrock Urban District, which in turn became the modern borough of Thurrock in 1974. Chadwell St Mary remains the name of one of Thurrock's Church of England parishes.
