Hazelbury Bryan is a village and civil parish in the county of Dorset in southern England. It is situated in the Blackmore Vale in the North Dorset administrative district, approximately 5 miles (8.0 km) southwest of the small town of Sturminster Newton. The parish includes the hamlets of Droop, Kingston, Parkgate, Pidney, Pleck, Wonston and Woodrow. In the 2011 UK census the parish had 480 dwellings, 454 households and a population of 1,059.
Sir Guy de Bryan, of Woodsford Castle, gave his surname to the village in the 14th century when he married the daughter of the First Earl of Salisbury.
The original settlement in the village is the hamlet of Droop, which is the location of the parish church. The church dates mostly from the 15th century, though it is perhaps the third building to have existed on the site. The other hamlets in the village are believed to have originated as a result of the Black Death twice afflicting the original settlement, and the villagers responding by burning it and rebuilding several smaller settlements on higher ground nearby.
