Great Baddow is an urban village in the Chelmsford borough of Essex, England. It is close to the county town, Chelmsford and, with a population of over 13,000, is one of the largest villages in the country.
Great Baddow's name is believed to have been derived from the River Beadwan, now known as the River Chelmer, which marks the northern boundary of the village. Beadwan is thought to be a Celtic word of uncertain meaning, possibly "birch stream" or a reference to the goddess Badbh. The centre of Great Baddow is now a Conservation Area and contains over 30 listed buildings.
