Granborough (previously Grandborough) is a village and civil parish in Buckinghamshire, England. It is around 5 miles (8 km) north of Waddesdon and 7 miles (11 km) south-east of Buckingham. The nearest town is Winslow.
The village name is Anglo-Saxon in origin, and means 'green hill'. In the Domesday Book of 1086 the village was recorded as Grenesberga.
The village is still one of the possessions of the Crown.
There is a public house, logically called the Crown. After the parish church the most interesting building is the neat half-timbered Arts and Crafts village hall. Granborough still has very many thatched cottages and houses, many of them in Green End, a hamlet attached to the village.
